A variety of substituted indoles and benzofurans are accessed via a platinum catalyzed annulation and vinylogous addition of enol nucleophiles. Several β-dicarbonyl compounds participate in the reaction, as do α-nitro and α-cyano carbonyl species. Subjecting the indole products to acidic conditions results in the formation of fused heterocycles.
通过铂催化的环化反应以及烯醇亲核试剂的插烯加成反应,可以得到多种取代吲哚和苯并呋喃。几种β-二羰基化合物以及α-硝基和α-氰基羰基化合物都参与了该反应。将吲哚产物置于酸性条件下会导致稠合杂环的形成。
