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

Department of Chemistry, Dr.Babasaheb Ambedkar Marathwada University, Aurangabad, Maharashtra 431004, India

Received Date: 13 September 2010

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.
