Abstract

A general and highly enantioselective method for the epoxidation of cis‐alkenylsilanes, in which the epoxysilanes were obtained with complete enantioselectivity in the presence of 0.5–2β€…mol % of a Ti–Salalen complex. The combination of this epoxidation method and the following transformations is a powerful approach that provides synthetically important epoxides, such as styrene oxides and geminally disubstituted epoxides, in enantiopure form.magnified image
