[Image: see text] A 1:2 mixture of ()- [()- = ()-3,5--Bu-4-MeO-MeOBIPHEP] and AgBF catalyzes the stereoconvergent, intermolecular enantioselective hydroamination of chiral, racemic 1,3-disubstituted allenes with -unsubstituted carbamates to form -allylic carbamates in good yield, with high regio- and diastereoselectivity, and up to 92% .
[图像:见正文](AuCl)[()-=()-3,5--Bu-4-MeO-MeOBIPHEP]与 AgBF 的 1:2 混合物作为催化剂,在手性、外消旋 1,3-二取代丙二烯与未取代的氨基甲酸酯的立体协同、分子间对映选择性氢胺化反应中,高产率、高区域和立体选择性地形成 -烯丙基氨基甲酸酯,ee 值最高可达 92%。
