  An enzyme-based synthesis of (S)-(−)-3-methyl-2-[(phenylsiilfonyl)-methyl]butyl phenyl sulfide and the stereochemical course of its alkylation

  摘要：

  The two title reactions have been explored. In the first instance, best results were achieved if the chloroacetate ester of 3-methyl-2[(phenylsulfonyl)methyl]-1-butanol was subjected to enzymatic hydrolysis with lipase P30 (Amano). Subsequent conversion to the sulfide of high optical purity (approximately 95% e.e.) was accomplished by means of tri-n-butylphosphine and diphenyl disulfide. The alkylation of this difunctional intermediate with several electrophiles has proven to be rather impressively diastereoselective. The relative (and absolute) course of these transformations has been established by means of X-ray crystallographic and NMR methods and is rationalized at the mechanistic level.
