Preparation of optically pure (3E,5E)-alkyl-2-hydroxy-6-arylhexa-3,5-dienoates by Candida parapsilosis ATCC 7330 mediated deracemisation of the racemates
摘要:
Biocatalytic deracemisation of a range of racemic (3E,5E)-alkyl-2-hydroxy-6-arylhexa-3,5-dienoates using Candida parapsilosis ATCC 7330 resulted in pure (S)-enantiomers in yields of up to 80% and ee > 99%. (C) 2007 Elsevier Ltd. All rights reserved.

A convenient and practical method for the selective reduction of C=O bond of a wide spectrum of α-keto β,γ-unsaturated esters via transfer hydrogenation reaction under the catalysis of Ru(p-cymene)(TsDPEN) (TsDPEN: monotosylated 1,2-diphenylethylene-1,2-diamine) was developed.
