described. This synthon contains an ester group in the side chain. The reaction of 10 with thiobenzoic S-acid and the amino acid Z-Val-OH yielded the racemic monothiodiamide 17 and the dipeptide 18 as a mixture of diastereoisomers, respectively (Scheme 2). From 18, each of the protecting groups was removed selectively (Scheme 3).
描述了一种新型的2,2-二取代的2 H-叠氮基-3-胺10的合成,作为外消旋Glu(2Me)的结构单元。该合成子在侧链中包含酯基。的反应10与硫代小号-酸和氨基酸Z-VAL-OH产生外消旋monothiodiamide 17和二肽18作为非对映体,分别为(的混合物反应路线2)。从18,选择性地除去每个保护基(方案3)。
