Abstract

A novel 1,3,2-diazaphospholidine (N-heterocyclic phosphine)-thiourea-mediated phospha-Mannich/intramolecular nucleophilic substitution reaction has been developed for the construction of an N-C-P bond unit. This transformation enabled a rapid access to cyclic tertiary α-amino phosphonates in one-pot procedure under additive-free mild reaction conditions. This study revealed the critical role of thiourea moiety of the N-heterocyclic phosphine-thiourea in the sequential intramolecular nucleophilic substitution reaction of the phosphonylation. © 2016 American Chemical Society.
