Synthesis of α-phosphorylated α,β-unsaturated imines and their selective reduction to vinylogous and saturated α-aminophosphonates

Palacios, Francisco,Vicario, Javier,Maliszewska, Agnieszka,Aparicio, Domitila

, p. 2682 - 2685 (2007)

An efficient synthesis of α,β-unsaturated imines derived from α-aminophosphonates is achieved through aza-Wittig reaction of P-trimethyl phosphazenes with β,γ-unsaturated α-ketophosphonates. Selective 1,2-reduction of such 1-azadienes affords β,γ-unsatura
