Continuous flow biocatalytic resolutions of methyl sulfinylacetates
摘要:
Product inhibition was encountered for some substrates in the resolution of methyl sulfinylacetates mediated by lipase Amano AK, so an apparatus to continually extract the carboxylate product was devised. This was applied to resolve some sulfoxides with high enantiodifferentiation. (C) 2011 Published by Elsevier Ltd.
[R′CH(OH)CHCHCO2R], which are ubiquitous structures in biologically active natural products and useful building blocks for organicsynthesis of chiral compounds. From the optically pure (R)-2-(2-benzothiazolylsulfinyl)acetates (>99% ee) prepared by the enzymatic kinetic resolution of (±)-2-(2-benzothiazolylsulfinyl)acetates, opticallyactive 4-hydroxyalk-2-enoates (up to 91% ee) have been obtained in good
