A variety of phosphorylated N-aryl and N-alkyl N-formyl and N-tert- butoxycarbonylaminomethyl derivatives have been efficiently prepared by treatment of the corresponding chloromethyl derivatives with a trialkyl phosphite or an alkyl diphenylphosphinite. These bifunctional compounds may be deprotonated with LDA and further submitted to electrophilic substitution. An acidic treatment of the resulting ...
