Microbiological and chemical methods in the asymmetric oxidation of sulfides: A comparative study for the preparation of (S)-vinyl sulfoxides
摘要:
The enantiogenicity of biological and chemical oxidation at the sulfur atom was studied on a series of prochiral vinyl sulfides for the preparation of sulfoxides of (S)-absolute configuration. Using either fungal cultures, Sharpless-modified reagent or chiral oxaziridine, the enantiomeric excesses varied according to the substrate's steric and/or electronic structure; the three methods were complementary.
