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.
Key words
aminophosphonates - multicomponent reactions - quaternary ammonium salts - green chemistry
- phosphorylations
