Five-component sequential Ugi/nucleophilic addition reaction of aromatic aldehydes, primary amines, propiolic acid, isocyanides, and hydrazides has been developed in order to access polyfunctional pseudopeptides. The reaction may proceed through formation of N-substituted 2-alkynamides as intermediates. This process is found to be mild and operationally simple with broad substrate scope.
为了获得多官能假肽,已开发出芳香族醛,伯胺,丙酸,异氰酸酯和酰肼的五组分顺序Ugi /亲核加成反应。该反应可以通过形成作为中间体的N-取代的2-炔基酰胺来进行。发现该过程温和且操作简单,具有广泛的基材范围。
