Asymmetric formal aza-Diels–Alder reactions with α,β-unsaturated ketones and 3H-indoles with disubstituted groups on the C3 position catalyzed by primary amine-thiourea bifunctional catalyst have been developed. The reactions produced chiral hexahydropyrido-[1,2-a]-indole-2-ones in high yields with excellent diastereo- and enantioselectivities.
已开发了伯胺-硫脲双功能催化剂催化的具有α,β-不饱和酮和3 H-吲哚在C3位带有双取代基的不对称形式氮杂-Diels -Alder反应。该反应以高产率产生具有优异的非对映选择性和对映选择性的手性六氢吡啶基-[1,2 - a ]-吲哚-2-酮。
