取代的含氨基亚甲基的有机磷化合物是氨基酸和天然焦磷酸盐的类似物,作为具有多种特性的有前途的配体和生物活性物质而备受关注[1]。以前,这种类型的一些化合物是使用各种甲酰胺衍生物合成的,如二烷基甲酰胺二烷基缩醛和乙氧基亚甲基亚胺 [2]。为了合成新型 N,N-二取代氨基亚甲基二膦酸盐,我们研究了三(三甲基甲硅烷基)亚磷酸酯与最常见的 N,N-二取代甲酰胺 A 的直接反应 [3]。甲酰脯氨酸 N 三甲基甲硅烷基醚 I 我们具体通过脯氨酸甲酰化,然后用双(三甲基甲硅烷基)胺和三甲基氯硅烷作为甲硅烷基化试剂在加热到 130°C 处理得到。内政部:10。

The new functionalized hydroxymethylphosphonic and methylenediphosphonic acids are synthesized via unique reaction of tris(trimethylsilyl) phosphite and N-formyl N-heterocycles, N-substituted 4-piperidones, 3-quinuclidone, and 2-adamantanone at the presence of effective catalyst – trimethylsilyl triflate under mild conditions.

Convenient methods for synthesis of various aminomethylenediphosphorus-containing acids and their derivatives starting from available trimethylsilyl esters of hypophosphorous and phosphorous acids, ethoxymethyleneimine hydrochlorides, and N-substituted formamides have been proposed. Selected properties of the obtained compounds have been examined.
