Mechanistic studies were performed for the clarification of the role of multifunctional Fei-Phos in allylic substitution reactions, in which it is proved to be a diphosphine-controlled catalytic asymmetric allylic alkylation.

We synthesized a series of phosphine–olefin-type chiral aminophosphines, and we confirmed that these each exists as two rotamers at the C(aryl)–N(amine) bond. We also investigated the ability of these aminophosphines to act as chiral ligands for Pd-catalyzed asymmetric allylic substitution reactions, such as the alkylation of allylic acetates with malonates or indoles, and we found they gave high enantio­selectivities (up to 98% ee).
