title: Conjugate addition of amines to an alpha,beta-unsaturated imine derived from alpha-aminophosphonate. Synthesis of gamma-amino-alpha-dehydroaminophosphonates.
abstract: Aza-Michael reaction of ammonia, aliphatic, aromatic and optically active amines to an alpha,beta-unsaturated imine derived from alpha-aminophosphonate affords alpha-dehydroaminophosphonates with a gamma-stereogenic center bearing an amino group. Resulting gamma-amino alpha-dehydroaminophosphonates can be used for the preparation of phosphorylated pyrimidine derivatives.
