Lithiation at C4 of the indole nucleus is readily directed by several functional groups. The 4-substituted indoles thus obtained are transformed into suitable substrates for metathesis reactions. Ring-closing metathesis effected on these compounds lead to skeletons related to several indole alkaloids.
几个官能团很容易指导吲哚核C4处的锂化。如此获得的4-取代的吲哚被转化为用于复分解反应的合适的底物。对这些化合物进行的闭环易位导致了与几种吲哚生物碱有关的骨架。
