Thiamine hydrochloride (VB1): An efficient catalyst for one-pot synthesis of α-aminophosphonates under ultrasonic irradiation
چکیده انگلیسی

An efficient synthesis of novel α-aminophosphonates by the reaction of aldehydes and amines with triethyl phosphite in the presence of the easily available, inexpensive, and nontoxic catalyst thiamine hydrochloride (VB1). This method affords the α-aminophosphonates under the influence of ultrasound irradiation in aqueous medium, in short reaction times (4–6 min), high yields (85–95%), with improved purity. The process is green, mild, inexpensive and excellent yields are the main compensation of this procedure.
