摘要
The preparation of diterbutyl-N (diphenylmethylene) aminomethylphosphonate 3 in four steps (42% overall yield) from N-hydroxymethyl phtalimide 1 is described. Various alpha-substituted alpha-aminophosphonic acids 5 containing functionalized unsaturated chains have been synthesized by alkylation of 3 under phase transfer catalysis with halides, Michael acceptors and palladium promoted reactions, followed by mild hydrolysis.
