For the purpose of studying the structure-activity relationship ofα-(substituted aniline)alkylphosphonate derivatives,a series of novelα-(substituted aniline)alkylphosphonates(1)was synthesized with substituted aniline and substituted benzaldehydes as starting materials reacting with dimethyl phosphite catalyzed by magnesium perchlorate.Compounds 1 reacted with t-Bu-NH 2 to gain 2-methylpropan-2-aminium O-alkylα-(substituted aniline)alkylphosphonate(2).The structures of compounds 2 were confirmed by 1H NMR,13 C NMR,IR,MS and elemental analys...
