Abstract
A rhodium/diphosphine-catalyzed asymmetric cross-dehydrogenative coupling between sulfoximines and dihydrosilanes has been achieved.This is the first report on the enantioselective N-silylation of sulfox-imines.The protocol gives access to a variety of Si-stereogenic N-silylated sulfoximines in decent yield(up to 99%)with excellent stereoselectivity(up to 99%),featuring high atom economy,and a cleaner manner with H2 as the sole byproduct.The obtained bis-Si-stereogenic monohydrosilane product can be further converted into the corresponding chiral polymer with pendant sulfoximine groups.
