A modified three-component condensation of 2-haloalkanamides, benzaldehydes and dialkyl phosphites leading to α-(2-haloacylamino)-substituted dialkyl benzylphosphonates 1 is described. Compounds 1 upon reaction with phthalimide and potassium carbonate under phase transfer catalysis conditions afford protected phosphonodipeptides, which can be used as important intermediates for the synthesis of oligophosphonopeptides.
描述了一种改进的三组分缩合反应,涉及2-卤代烷酰胺、苯醛和二烷基膦酸酯,最终生成α-(2-卤代酰基氨基)-取代的二烷基苯基膦酸酯1。化合物1与邻苯二甲酰亚胺和碳酸钾在相转移催化条件下反应,生成保护的膦酸二肽,这些二肽可以作为合成寡膦肽的重要中间体。
