We report in this paper an interesting tandem reaction involving sequential palladium(0)-catalyzed decarboxylation of diynylic carbonates, intramolecular nucleophilic cyclization and Schmittel reaction, which provides a facile method for the synthesis of a variety of polycyclic benzo[b]fluorene derivatives from easily accessible starting materials.
我们在本文中报道了一个有趣的串联反应,该反应涉及依次进行钯(0)催化的二炔碳酸酯的脱羧反应,分子内亲核环化反应和施密特反应,这为轻松地合成各种多环苯并[ b ]芴衍生物提供了一种简便的方法。可访问的起始材料。
