Asymmetric intramolecular palladium-catalyzed allylic alkylation allowing access to disubstituted sulfinyl γ-lactams is described. The use of unsaturated amides bearing a sulfinyl group of defined absolute configuration together with enantiopure BINAP as the ligand in a biphasic medium provided good diastereoselectivities with clear solvent effect.
描述了不对称的分子内
钯催化的烯丙基烷基化,其允许接近二取代的亚磺酰基γ-内酰胺。在双相介质中使用具有定义的绝对构型的亚磺酰基的不饱和酰胺与对映体BINAP一起作为
配体在双相介质中提供了良好的非对映选择性,并具有明显的溶剂作用。
