The first synthesis of the acyl side-chain segment of polyoxypeptin, a potent inducer of apoptosis in human pancreatic carcinoma AsPC-1, was accomplished. The key feature of the present synthesis is the stereospecific palladium-catalyzed hydrogenolysis of (Z)-alkenyloxirane to anti-hydroxyalkenoate by an improved method.
首次合成了多氧合肽素的酰基侧链片段,后者是人胰腺癌AsPC-1的有效凋亡诱导剂。本合成的关键特征是通过改进的方法,立体定向钯催化的(Z)-烯基环氧乙烷的氢解为抗-羟基烯酸酯。
