A process for the asymmetric synthesis of amines which comprises the amination of a conjugated diene having from 4 to about 20 carbon atoms in the presence of a catalyst system comprising a palladium compound and an optically active phosphine ligand containing at least two phosphorus atoms.
Hydrogen-bond-activated C-N bond cleavage of allylic amines was realized in Pd-catalyzed allylic alkylation to form the C-C bond product. The method could be expanded to a series of allylic amines and carbonyl compounds with excellent results. It provides a new and convenient access to C-C bond formation based on Pd-catalyzed allylic alkylation of allylic amines by using only inexpensive alcohol solvents.
烯丙胺的氢键活化 CN 键断裂是在 Pd 催化的烯丙基烷基化中实现的,以形成 CC 键产物。该方法可以扩展到一系列烯丙基胺和羰基化合物,并取得了优异的结果。它通过仅使用廉价的醇溶剂,为基于 Pd 催化的烯丙基胺的烯丙基烷基化形成 CC 键提供了一种新的便捷途径。
