Highly Enantioselective Aza-Baylis-Hillman-Type Reaction of alpha,beta-Unsaturated Aldehydes with In Situ Generated N-Boc- and N-Cbz-Imines

[摘要]：An organocatalytic highly enantioselective aza-Baylis-Hillman reaction of alpha,beta-unsaturated aldehydes with in situ generated N-Boc- and N-Cbz-imines is presented. This novel process opens the pathway for the synthesis of beta-amino carbonyl compounds bearing an alpha-alkylidene group under mild and simple conditions. ((C) Wiley-VCH Verlag GmbH & Co.
