“…16a-c It has been reported that they show promise when utilized in applications such as peptidomimetics, enzyme inhibitors, pharmacogenic agents, antibiotics, antihypertensives, antitumor agents, antiviral species, anti-metabolites, and herbicides. 17,18a-e The synthesis of α-aminophosphonates through Kabachnik-Fields condensation has been performed using a variety of Lewis acids such as metal salts like Mg (ClO 4 ) 2 , 19 GaI 2 , 20 LiClO 4 , 21 and metal triflates (M(OTf ) n , M = Li, Mg, Al, Cu, Ce, Yb, Sm, Sc, La) 22,23 as well as Brønsted acids such as hypophosphorous acid, 24 sulfamic acid, 25 and oxalic acid. 26 However, these conventional methods have several drawbacks, such as long reaction times, high reaction temperatures, low yields of products, and the use of hazardous reagents and solvents.…”
