Abstract
A new class of α-aminophosphonates 2–16 has been synthesized by the reaction of equimolar quantities of Schiff's bases with diethyl/dimethyl/diphenyl phosphite in dry toluene under reflux conditions using tetramethylguanidine (TMG) as a catalyst via Pudovik reaction in high yields (78–89%). The structures of the title compounds have been established by elemental; infrared (IR); 1H-, 13C-, and 31P-NMR; and mass spectral data analyses. They were found to possess significant antimicrobial and antioxidant activity. Supplemental materials are available for this article.
