A Combined Spectroscopic and Computational Study on the Mechanism of Iron-Catalyzed Aminofunctionalization of Olefins Using Hydroxylamine Derived N-O Reagent as the "Amino" Source and "Oxidant".

Herein, we study the mechanism of iron-catalyzed direct synthesis of unprotected aminoethers from olefins by a hydroxyl amine derived reagent using a wide range of analytical and spectroscopic techniques (Mössbauer, Electron Paramagnetic Resonance, Ultra-Violet Visible Spectroscopy, X-ray Absorption, Nuclear Resonance Vibrational Spectroscopy, and resonance Raman) along with high-level quantum chemical calculations. The hydroxyl amine derived triflic acid salt acts as the "oxidant" as well as "amino" group donor. It activates the high-spin Fe(II) (St = 2) catalyst [Fe(acac)2(H2O)2] (1) to generate a high-spin (St = 5/2) intermediate (Int I), which decays to a second intermediate (Int II) with St = 2. The analysis of spectroscopic and computational data leads to the formulation of Int I as [Fe(III)(acac)2-N-acyloxy] (an alkyl-peroxo-Fe(III) analogue). Furthermore, Int II is formed by N-O bond homolysis. However, it does not generate a high-valent Fe(IV)(NH) species (a Fe(IV)(O) analogue), but instead a high-spin Fe(III) center which is strongly antiferromagnetically coupled (J = -524 cm-1) to an iminyl radical, [Fe(III)(acac)2-NH·], giving St = 2. Though Fe(NH) complexes as isoelectronic surrogates to Fe(O) functionalities are known, detection of a high-spin Fe(III)-N-acyloxy intermediate (Int I), which undergoes N-O bond cleavage to generate the active iron-nitrogen intermediate (Int II), is unprecedented. Relative to Fe(IV)(O) centers, Int II features a weak elongated Fe-N bond which, together with the unpaired electron density along the Fe-N bond vector, helps to rationalize its propensity for N-transfer reactions onto styrenyl olefins, resulting in the overall formation of aminoethers. This study thus demonstrates the potential of utilizing the iron-coordinated nitrogen-centered radicals as powerful reactive intermediates in catalysis

Hydroxylamine‐derived Reagent as a Dual Oxidant and Amino Group Donor for the Iron Catalyzed Preparation of Unprotected Sulfinamides from Thiols

An iron catalyzed reaction for the selective transformation of thiols (‐SH) to sulfinamides (‐SONH 2 ) by a direct transfer of ‐ O and free ‐ NH 2 groups has been developed. The reaction operates under mild conditions using a bench stable hydroxylamine derived reagent, exhibits broad functional group tolerance, is scalable and proceeds without the use of any precious metal catalyst or additional oxidant. This novel, practical reaction leads to the formation of two distinct new bonds (S=O and S–N) in a single step to chemoselectively form valuable, unprotected sulfinamide products. Preliminary mechanistic studies implicate the role of the alcoholic solvent as an oxygen atom donor.ISSN:1433-7851ISSN:1521-3773ISSN:0570-083

Oxygenative Aromatic Ring Cleavage of 2‑Aminophenol with Dioxygen Catalyzed by a Nonheme Iron Complex: Catalytic Functional Model of 2‑Aminophenol Dioxygenases

2-Aminophenol dioxygenases catalyze the oxidative ring cleavage of 2-aminophenol to 2-picolinic acid using O₂ as the oxidant. Inspired by the reaction catalyzed by these nonheme iron enzymes, a biomimetic iron­(III)-2-amidophenolate complex, [(<i>t</i>Bu-L^Me)­Fe^III(4,6-di-<i>t</i>Bu-AP)]­(ClO₄) (<b>1a</b>) of a facial tridentate ligand (<i>t</i>Bu-L^Me = 1-[bis­(6-methyl-pyridin-2-yl)-methyl]-3-<i>tert</i>-butyl-urea and 4,6-di-<i>t</i>Bu-H₂AP = 2-amino-4,6-di-<i>tert</i>-butylphenol) bearing a urea group have been isolated. The complex reacts with O₂ to cleave the C–C bond of 4,6-di-<i>t</i>Bu-AP regioselectively and catalytically to afford 4,6-di-<i>tert</i>-butyl-2-picolinic acid. An iron­(II)-chloro complex [(<i>t</i>Bu-L^Me)­Fe^IICl₂(MeOH)] (<b>1</b>) of the same ligand also cleaves the aromatic ring of 4,6-di-<i>t</i>Bu-AP catalytically in the reaction with O₂. To assess the effect of urea group on the ring cleavage reaction of 2-aminophenol, two iron complexes, [(BA-L^Me)₂Fe^II₂Cl₄] (<b>2</b>) and [(BA-L^Me)­Fe^III(4,6-di-<i>t</i>Bu-AP)]­(ClO₄) (<b>2a</b>), of a tridentate ligand devoid of urea group (BA-L^Me = benzyl-[bis­(6-methyl-pyridin-2-yl)-methyl]-amine) have been isolated and characterized. Although the iron complexes (<b>1</b> and <b>1a</b>) of the ligand with urea group display catalytic reaction, the iron complexes (<b>2</b> and <b>2a</b>) of the ligand without urea group do not exhibit catalytic aromatic ring fission reactivity. The results support the role of urea group in directing the catalytic reactivity exhibited by <b>1</b> and <b>1a</b>

Oxygenation of Organoboronic Acids by a Nonheme Iron(II) Complex: Mimicking Boronic Acid Monooxygenase Activity

Phenolic compounds are important intermediates in the bacterial biodegradation of aromatic compounds in the soil. An <i>Arthrobacter sp.</i> strain has been shown to exhibit boronic acid monooxygenase activity through the conversion of different substituted phenylboronic acids to the corresponding phenols using dioxygen. While a number of methods have been reported to cleave the C–B bonds of organoboronic acids, there is no report on biomimetic iron complex exhibiting this activity using dioxygen as the oxidant. In that direction, we have investigated the reactivity of a nucleophilic iron–oxygen oxidant, generated upon oxidative decarboxylation of an iron­(II)–benzilate complex [(Tp^Ph2)­Fe^II(benzilate)] (Tp^Ph2 = hydrotris­(3,5-diphenyl-pyrazol-1-yl)­borate), toward organoboronic acids. The oxidant converts different aryl/alkylboronic acids to the corresponding oxygenated products with the incorporation of one oxygen atom from dioxygen. This method represents an efficient protocol for the oxygenation of boronic acids with dioxygen as the terminal oxidant

Gallic Acid Enriched Fraction of Phyllanthus emblica Potentiates Indomethacin-Induced Gastric Ulcer Healing via e-NOS-Dependent Pathway

The healing activity of gallic acid enriched ethanolic extract (GAE) of Phyllanthus emblica fruits (amla) against the indomethacin-induced gastric ulceration in mice was investigated. The activity was correlated with the ability of GAE to alter the cyclooxygenase- (COX-) dependent healing pathways. Histology of the stomach tissues revealed maximum ulceration on the 3rd day after indomethacin (18 mg/kg, single dose) administration that was associated with significant increase in inflammatory factors, namely, mucosal myeloperoxidase (MPO) activity and inducible nitric oxide synthase (i-NOS) expression. Proangiogenic parameters such as the levels of prostaglandin (PG) E2, vascular endothelial growth factor (VEGF), hepatocyte growth factor (HGF), von Willebrand Factor VIII, and endothelial NOS (e-NOS) were downregulated by indomethacin. Treatment with GAE (5 mg/kg/day) and omeprazole (3 mg/kg/day) for 3 days led to effective healing of the acute ulceration, while GAE could reverse the indomethacin-induced proinflammatory changes of the designated biochemical parameters. The ulcer healing activity of GAE was, however, compromised by coadministration of the nonspecific NOS inhibitor, N-nitro-L-arginine methyl ester (L-NAME), but not the i-NOS-specific inhibitor, L-N6-(1-iminoethyl) lysine hydrochloride (L-NIL). Taken together, these results suggested that the GAE treatment accelerates ulcer healing by inducing PGE2 synthesis and augmenting e-NOS/i-NOS ratio

Reactivity of an Iron–Oxygen Oxidant Generated upon Oxidative Decarboxylation of Biomimetic Iron(II) α‑Hydroxy Acid Complexes

Three biomimetic iron­(II) α-hydroxy acid complexes, [(Tp^Ph2)­Fe^II(mandelate)­(H₂O)] (<b>1</b>), [(Tp^Ph2)­Fe^II(benzilate)] (<b>2</b>), and [(Tp^Ph2)­Fe^II(HMP)] (<b>3</b>), together with two iron­(II) α-methoxy acid complexes, [(Tp^Ph2)­Fe^II(MPA)] (<b>4</b>) and [(Tp^Ph2)­Fe^II(MMP)] (<b>5</b>) (where HMP = 2-hydroxy-2-methylpropanoate, MPA = 2-methoxy-2-phenylacetate, and MMP = 2-methoxy-2-methylpropanoate), of a facial tridentate ligand Tp^Ph2 [where Tp^Ph2 = hydrotris­(3,5-diphenylpyrazole-1-yl)­borate] were isolated and characterized to study the mechanism of dioxygen activation at the iron­(II) centers. Single-crystal X-ray structural analyses of <b>1</b>, <b>2</b>, and <b>5</b> were performed to assess the binding mode of an α-hydroxy/methoxy acid anion to the iron­(II) center. While the iron­(II) α-methoxy acid complexes are unreactive toward dioxygen, the iron­(II) α-hydroxy acid complexes undergo oxidative decarboxylation, implying the importance of the hydroxyl group in the activation of dioxygen. In the reaction with dioxygen, the iron­(II) α-hydroxy acid complexes form iron­(III) phenolate complexes of a modified ligand (Tp^Ph2*), where the ortho position of one of the phenyl rings of Tp^Ph2 gets hydroxylated. The iron­(II) mandelate complex (<b>1</b>), upon decarboxylation of mandelate, affords a mixture of benzaldehyde (67%), benzoic acid (20%), and benzyl alcohol (10%). On the other hand, complexes <b>2</b> and <b>3</b> react with dioxygen to form benzophenone and acetone, respectively. The intramolecular ligand hydroxylation gets inhibited in the presence of external intercepting agents. Reactions of <b>1</b> and <b>2</b> with dioxygen in the presence of an excess amount of alkenes result in the formation of the corresponding <i>cis</i>-diols in good yield. The incorporation of both oxygen atoms of dioxygen into the diol products is confirmed by ¹⁸O-labeling studies. On the basis of reactivity and mechanistic studies, the generation of a nucleophilic iron–oxygen intermediate upon decarboxylation of the coordinated α-hydroxy acids is proposed as the active oxidant. The novel iron–oxygen intermediate oxidizes various substrates like sulfide, fluorene, toluene, ethylbenzene, and benzaldehyde. The oxidant oxidizes benzaldehyde to benzoic acid and also participates in the Cannizzaro reaction
