indole-oxazole scaffold is found in a range of biologically active natural products, including the breitfussin family. Divergent methods that provide access to the indole-oxazole template are relatively scarce, which impedes the wider exploration of these natural products and their exciting biological activity. Herein, we describe a highly divergent synthesis of the indole-oxazole scaffold via a one-pot
吲哚-恶唑支架存在于一系列具有生物活性的天然产物中,包括 breitfussin 家族。提供获得吲哚-恶唑模板的发散方法相对稀缺,这阻碍了对这些天然产物及其令人兴奋的生物活性的更广泛探索。在此,我们描述了通过一锅 Friedel-Crafts/Robinson-Gabriel 合成高度发散的吲哚-恶唑支架合成,以及该方法在 breitfussins C、G 和 H 合成中的应用。
