An enantio- and diastereoselective direct vinylogous Mannich reaction of alpha,alpha-dicyanoolefins and N-sulfonyl alkylimines has been developed by the catalysis of a new family of bifunctional organocatalysts merging chiral BINOL and 9-amino-9-deoxyepi-cinchona alkaloid skeletons, from which chiral beta-, delta- or gamma-amino compounds could be efficiently derived.
对映体和非对映体选择性的α,α-二氰基烯烃和N-磺酰基烷基亚胺的直接乙烯基乙烯基曼尼希反应是通过催化合并手性BINOL和9-氨基-9-脱氧表皮-金鸡纳生物碱骨架的双官能团有机催化剂的新反应而开发的。可以有效地衍生出哪些手性β-,δ-或γ-氨基化合物。
