A short route to the marine natural product aspergillamide B has been developed. The key step is the stereoselective formation of the trans indole–enamide pharmacophore by indole-assisted dehydration from the functionalized aminoalcohol intermediate. HPLC and 1H NMR analyses show that aspergillamide B is more stable in the cis rotamer form.
已经开发出一种短途途径来生产海洋天然产物曲霉酰胺B。关键步骤是通过吲哚辅助从功能化氨基醇中间体中脱水来形成反式吲哚-烯酰胺药效团的立体选择性。HPLC和1 H NMR分析表明,曲霉酰胺B以顺式旋转异构体形式更稳定。
