general, efficient, and conceptually new approach to the total syntheses of marine-derived indole alkaloids, including (+/-)-flustramines A (1) and B (2), (+/-)-flustramides A (3) and B (4), and (+/-)-debromoflustramine B (5), is outlined. The key step in the syntheses involves the conjugated addition of an organomagnesium species derived from prenyl bromide to 2-hydroxyindolenines. Compounds 1, 2, and
一种通用,有效且概念上新颖的海洋衍生吲哚生物碱总合成方法,包括(+/-)-氟雌胺A(1)和B(2),(+/-)-氟雌酰胺A(3)和概述了B(4)和(+/-)-去溴氟胺B(5)。合成中的关键步骤涉及将异戊烯基溴化物衍生的有机镁物种共轭添加到2-羟基吲哚啉中。化合物1、2和5已分五步合成,总产率分别为23%,17%和16%,而氟他酰胺3和4仅通过四步合成,总产率分别为24%和18%。 ,基于2-羟基吲哚胺。
