A model compound bearing the C1–C17 fragment of carzinophilin was synthesized. The synthesis involved coupling reaction of a cyclic thioimidate with the 4H-oxazol-5-one derivative, ring-opening of the 4H-oxazol-5-one to furnish a dehydropeptide system, elaboration of the C1–C6 enolamide, and construction of the aziridine ring as key steps.
合成了带有carzinophilin C1-C17片段的模型化合物。合成参与耦合的环状硫代亚氨酸酯的反应与4 ħ -恶唑-5-酮衍生物,其4的开环ħ -恶唑-5-酮,得到一个dehydropeptide系统,所述C1-C6 enolamide的阐述,和建筑氮丙啶环的键是关键步骤。
