N-Aminoamide pseudodipeptides ZAAΨ[CO-N(NPht)]-AAOR can be easily obtained via the Mitsunobu protocol by using α-hydroxyesters as alcohol partners and aminoacid phthaloyl hydrazide derivatives as acidic partners. The direct conversion of the phthaloyl group into tert-butyloxycarbonyl can be performed in a three-stage one-pot protocol.
N-氨基酰胺假二肽ZAAΨ[CO-N(NPht)]-AAOR可以通过Mitsunobu方案轻松获得,方法是将α-羟基酯用作醇配偶体并将氨基酸邻苯二甲酰肼衍生物用作酸性配偶体。邻苯二甲酰基向叔丁氧基羰基的直接转化可以在三阶段一锅法中进行。
