Efficient total syntheses of heteromines A and B (antitumor compounds previously isolated from the plant Heterostemma brownii Hayata) from commercially available 2-amino-6-chloropurine have been developed. The synthesis of heteromine A is considerably shorter than the previously reported synthesis, only requiring four steps, whereas the iodide salt of heteromine B was prepared in five steps. Heteromines
已经开发了从可商购的2-氨基-6-氯嘌呤有效合成总的杂胺A和B(先前从植物杂种异叶菊(Heterostemma brownii Hayata)中分离的抗肿瘤化合物)。杂胺A的合成比以前报道的合成短得多,仅需要四个步骤,而杂胺B的碘盐是在五个步骤中制备的。异源A和B没有显示出明显的抗菌活性,因此对癌细胞系具有选择性。
