A convenient route for the synthesis of novel amides containing at least one β-keto-α,α-difluoromethylenephosphonate group has been elaborated. The procedure requires simple stirring of an amine and difluoro(diethoxyphosphoryl)acetyl chloride in THF in the presence of a catalytic amount of DMAP. A wide range of amines has been accepted, including aliphatic and aromatic diamines, diaminobenzidine or
已经阐明了合成含有至少一个β-酮-α,α-二氟亚甲基膦酸酯基团的新型酰胺的简便途径。该过程需要在催化量的DMAP的存在下,简单地搅拌胺和二氟(二乙氧基磷酰基)乙酰氯在THF中的搅拌。广泛的胺已被接受,包括脂族和芳族二胺,二氨基联苯胺或胺衍生物,例如环丙沙星。
