摘要
Based on the conjugate addition-silyl migration-alkylation strategy, (Z)-silyl enol ethers possessing a stereocenter at the gamma-position were prepared with complete regio- and stereoselectivity by three-component coupling of alpha,beta-unsaturated acylsilanes, Grignard reagents (or cuprates)/copper(I) tert-butoxide, and organic halides.
