N-Boc-protected 3-iodoindoles and 3-iodo-7-azaindole in a pseudo three-component reaction involving a one-pot Masuda borylation–Suzuki arylation sequence. Some of the title compounds display promising cytotoxic properties. The versatility of this methodology is illustrated by a very concise total synthesis of the marine alkaloid hyrtinadine A.
二嗪桥连的双吲哚很容易从 N-Boc 保护的 3-碘代吲哚和 3-碘-7-氮杂吲哚在伪三组分反应中获得,该反应涉及一锅 Masuda 硼酸化 - Suzuki 芳基化序列。一些标题化合物显示出有希望的细胞毒性特性。海洋生物碱 hyrtinadine A 的非常简洁的全合成说明了这种方法的多功能性。
