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
多种磷酸化的ñ -芳基和Ñ烷基Ñ甲酰基和ñ -叔-butoxycarbonylaminomethyl衍生物通过用三烷基亚磷酸酯或烷基diphenylphosphinite相应氯甲基衍生物的被有效地制备。这些双功能化合物可以用LDA去质子化,并进一步进行亲电取代。所得化合物的酸性处理产生N-芳基和N-烷基氨基(烷基)膦酸酯和氧化膦。
