Enantioselective acylation of chroman-4-ols catalysed by lipase from Pseudomonas cepecia (Amano PS)
摘要:
Lipase Amano PS catalysed acylation of (+/-)-chroman-4-ols using vinyl acetate as the acyl donor in n-hexane gave (R)-(+)-chroman-4-ol acetates and (S)-(-)-chroman-4-ols in high enantiomeric excess. The relationship between the position of the substituents in the chroman-4-ol to the ee and the spatial characteristics of the enzyme active site are proposed. (C) 1997 Elsevier Science Ltd.
