A stereocontrolled synthesis of the (E)-alkene dipeptide isostere of Trp-Val is described. The stereospecific α-alkylation of the δ-amino-γ-mesyloxy-α, β-unsaturated ester via the organocyanocopper-Lewis acid mediated reaction, based on 1, 3-transfer of chirality, was successfully applied for the key step in the synthetic sequence.
报道了(E)-烯烃二肽类似物Trp-Val的手性控制合成方法。通过基于手性1,3传递的有机氰铜-路易斯酸介导反应,成功实现了δ-氨基-γ-甲磺酰氧基-α,β-不饱和酯的立体选择性α-烷基化,这一关键步骤在合成序列中得以应用。
