11-(4-Meth­oxy­phen­yl)-3,3-dimethyl-2,3,4,5,10,11-hexa­hydro-1H-dibenzo[b,e][1,4]diazepin-1-one monohydrate

In the title compound, C22H24N2O2·H2O, the co-crystallized water mol­ecule inter­acts with the N and O atoms of the mol­ecule through Ow—H⋯N, Ow—H⋯O(meth­yl) and N—H⋯Ow hydrogen-bonding inter­actions. These hydrogen bonds, along with the inter­molecular N—H⋯O=C hydrogen-bonding inter­actions, connect the mol­ecules into a three-dimensional network. The dihedral angle between the two aromatic rings is 65.46 (10)°

Synthesis of 2-Chloro-3-(2-naphthyloxy)quinoxaline

A mixture of 2,3-dichloroquinoxaline 1 [1] (1.0 g, 5 mmol) and 2-naphthol (0.72 g, 5 mmol) in pyridine (10 mL) was heated to 130°C for 3 h, with magnetic stirring, to give a dark-brown reaction mixture.[...

Synthesis and Some Reactions of 3-Chloro-2-(cyanomethylene)-1,2-dihydroquinoxalines

2,3-Dichloroquinoxaline and some of its derivatives have been reacted with malononitrile and ethyl cyanoacetate to yield a variety of 3-chloro-2-(cyanomethylene)- 1,2-dihydroquinoxaline derivatives. The reaction of 3-chloro-2-(dicyanomethylene)-1,2- dihydroquinoxaline (2e) with pyridine and its methyl derivatives led to the zwitterionic structures 6a-6c. The structures of the newly synthesized compounds were assigned by spectroscopic data and elemental analyses

Isolation, characterization, crystal structure, free radical scavenging- and computational studies of 9-[-4(propan-2-yl)pheny]-3,4,5,6,7,9-hexahydro-1H-xanthene-1,8(2H)-dione from Garcinia kola seeds

ceylan, umit/0000-0002-1461-9889WOS: 000403855700047A new crystallographic form of a pure xanthenedione derivative (11'), C22H24O3, was isolated from the hexane extract of the seeds of Garcinia kola. The structure of the compound was determined on the basis of FTIR and NMR spectroscopy and confirmed by single-crystal X-ray diffraction analysis. The compound crystallized as C22H24O3 H2O H3O+ Cl-, as the result of the extraction process, adopts monoclinic, space group P21/n (no. 14) and is stabilized by OW-H center dot center dot center dot OW, OW-H center dot center dot center dot Cl, C-H center dot center dot center dot OW, C-H center dot center dot center dot Cl intramolecular hydrogen bonds and weak OW-H center dot center dot center dot O, C-H center dot center dot center dot O, intermolecular interactions forming a 3-D supramolecular structure. The molecular property of the pure xanthene derivative, C22H24O3, has also been investigated using the density functional theory (DFT) method. The calculated IR, H-1 and C-13 data were found to be in good agreement with experimental values. The compound C22H24O3 showed weak DPPH radical scavenging activity with IC50 value of 2.37 +/- 0.08 mg/ml. (C) 2017 Elsevier B.V.
