Factors influencing the reaction yields and formation of the side products during coupling of N-carbobenzoxyamino acids with dialkyl or diphenyl aminoalkylphosphonates, by means of mixed anhydride procedure, were evaluated. The recommended procedure, arising from these studies, involves the use of chloroform/ethyl chloroformate/triethylamine system and delicate warming of the reaction mixture during

group-directed and amino-self-directed Pd-catalyzed α-aminophosphonate side-chain C(sp3)-Harylation. Both strategies showed facile, efficient, and single regioselectivity in the reaction between free α-aminophosphonates and aryl iodides. Furthermore, the modification of amino and late-stage functionalization of the C(sp3)-P bond from products indicates potential applications for α-aminophosphonates.
