摘　　要：α-烷氧酰胺亚甲基膦酸酯由于亚甲基结构的特殊性使得其合成方法很有限,针对该问题研究了这一类型化合物的合成方法学.以乙酸乙酯作为溶剂,在氢氧化锂碱性条件下,α-芳磺酰亚甲基氨基甲酸酯与磷酸二酯反应能以良好至中等的产率顺利地合成常见方法难以合成的α-烷氧酰胺亚甲基膦酸酯.该方法操作简便,条件温和,并可应用于克级规模反应.Methods for the synthesis of α-alkoxycarbonylaminomethylphosphonates are very limited because of the presence of unique methylene group in their structures. Thus the methodology for the synthesis of this kind of compounds is studied. Under the basic conditions of using Li OH, α-sulfonylmethylcarbamates reacted with dialkylphosphonates in the solvent of commercial Et OAc giving the products of α-alkoxycarbonylaminomethylphosphonates which are typically hard to be synthesized in good to moderate yields. This simple protocol runs under very mild conditions, and can be exploited for multigram amounts with good yield too.
