Abstract
A simple and highly efficient approach has been developed for a multicomponent one-pot reaction of aldehydes or ketones with amines and diethyl or triethyl phosphite to give the corresponding α-aminophosphonates. In the presence of quaternary ammonium salts, which are environmental friendly, inexpensive, and recyclable, α-aminophosphonates were obtained in excellent yields at room temperature within short times.
