Abstract

The use of quaternary ammonium salts, which are environmental friendly, inexpensive, and recyclable enables a simple and highly efficient multicomponent reaction of aldehydes or ketones with amines and diethyl or triethyl phosphite to give the corresponding α-aminophosphonates in excellent yields at room temperature.
