Regio- and stereoselective hydrogenolysis of optically active diols via transfer hydrogenation: Synthesis of ɑ-arylpropionic acids

1221-122

A Selective, Efficient and Environmentally Friendly Method for the Oxidative Cleavage of Glycols

A catalytic methodology for the oxidative cleavage of vicinal diols is described as an advantageous alternative in terms of the environmental impact on classical methods involving toxic oxidants. The novel strategy is based on the use of dioxomolybdenum(VI) complexes as catalysts and dimethyl sulfoxide (DMSO) as an oxidant and displays high selectivity and a broad scope for glycol cleavage. In addition, the developed system is also useful for the oxidation of acyloins to diketones.Ministerio de Economía y Competitividad (MINECO) and FEDER (CTQ2013-48937-C2-1-P) and Junta de Castilla y León (BU237U13

Cu-exchanged Y-zeolite: A heterogeneous catalyst for the synthesis of α-aminoketones

515-517Cu-zeolite catalyzes the amination of silyl enol ethers using PhI= NTs producing α-amino ketones in good yields

Enantioselective synthesis of (<i style="">S</i>)-<i style=""><img src='/image/spc_char/alpha.gif' border=0></i>-arylpropionic acids <i style="">via</i> Pd-catalyzed kinetic resolution of benzylic alcohols

557-562A convenient synthetic route for the synthesis of three (S)-a-propionic acids, (S)-naproxen (90% ee), (S)-ibuprofen (82% ee) and (S)-phenylpropionic acid (92% ee) is described. Pd-catalyzed oxidative kinetic resolution of the corresponding benzylic alcohols is used as a key step to introduce stereogenicity into the molecule

Neodymium acetylacetonate. A new heterogeneous catalyst for transfer hydrogenation of carbonyl compounds

409-410Neodymium acetylacetonate, Nd (acac)3 3H2O, has been found to exhibit high activity towards the transfer hydrogenation of carbonyl compounds using 2-propanol as hydrogen source under truly heterogeneous phase to afford the corresponding alcohols in 63-81% yield
