  A novel generation of optically active ethyl 4-chloro-3-hydroxybutyrate as a C4 chiral building unit using microbial dechlorination

  摘要：

  A novel procedure for the generation of optically active ethyl 4-chloro-3-hydroxybutyrate using bacterial cells was developed. Ethyl (S)-4-chloro-3-hydroxybutyrate was prepared by Pseudomonas sp. OS-K-29, which stereoselectively assimilates 2,3-dichloro-1-propanol. The reaction was based on its kinetic dehalogenation for both enantiomers using the resting cells. The obtained 4-chloro-3-hydroxybutyrate rate had high enantiomeric excess of >98%, with a yield of 33% at the microbial resolution step. Moreover, several C4 compounds having the 4-chloro-3-hydroxyl function were also resolved and gave good enantiomeric purities (>95 %ee). Ethyl (R)-4-chloro-3-hydroxybutyrate was also obtained with high enantiomeric purity (>98 %ee) using the cells of Pseudomonas sp DS-K-NR818. Copyright (C) 1996 Elsevier Science Ltd

  A new dinuclear chiral Co(salen) complexes bearing group 13 metals have been synthesized and characterized. The easily prepared complexes exhibited very high catalytic reactivity and enantioselectivity for the asymmetric ring opening of epoxides with H2O, chloride ions and carboxylic acids and consequently provide enantiomerically enriched terminal epoxides (>99% ee). It also catalyzes the asymmetric
