摘要

Alkyl aryl sulfides were enantioselectively oxidized in the crystalline cyclodextrin (CD) complexes under varioue conditions. The oxidation of alkyl phenyl sulfoxides in the j3- cyclodextrin (8-CD) complexes resulted in higher chiral induction than that in the a-CD complexes. Methyl 1-or 2-naphthyl sulfides were oxidized more enantioselectively in j3-CD than in yCD. By changing the methyl substituent of 1-naphthyl sulfide to an isobutyl group, ...
