Chemoenzymatic approaches to obtain chiral-centered selenium compounds
摘要:
The synthesis of chiral-centered selenium compounds is presented. Enantioselective oxidations of these organoselenium compounds were performed using a wide range of biocatalysts, including Baeyer-Villiger monooxygenases, oxidoreductases-containing Aspergillus terreus and lipase (Cal-B) in the presence of oxidants. Finally, efficient synthesis of enantiopure organoselenium compounds using a kinetic resolution approach mediated by Cal-B was achieved. (C) 2012 Elsevier Ltd. All rights reserved.

Alcohols, ethers, and esters were directly converted to the corresponding alkyl phenyl selenides by the reaction of diphenyldiselenide and the La/Me3SiCl/cat.I2/cat.CuI. It was suggested that alkyl phenyl selenides were formed by the SH2 type reaction of diphenyldiselenide with alkyl radicals generated from alcohols, ethers or esters.
