摘要

Abstract The electrophilic enantioselective sulfenylation of 1, 3-dicarbonyl compounds with phenylsulfenyl chloride is effectively catalyzed by [Ti (TADDOLato)] complexes. The corresponding products are obtained in moderate to high yields. The highest ee values (up to 97%) are obtained in toluene at room temperature and with a typical catalyst loading of 5 mol%. Bulky ester groups and sterically undemanding substituents at the α-position were ...
