Highly efficient synthesis of chiral β-hydroxy sulfides with high enantiomeric purity via CBS-oxazaborolidine-catalyzed borane reduction
摘要:
A simple and efficient synthesis of chiral beta-hydroxy p-tolylsulfides with high enantiomeric purity by CBS-oxazaborolidine-catalyzed asymmetric borane reduction of beta-keto p-tolyisulfides using N-ethyl-N-isopropylaniline-borane complex as the borane carrier is reported.
