Rapid access: The title reaction generates highly functionalized benzo‐annulated heterocycles and heterobiaryls. This method is amenable to a diverse array of heteroaromatics, thus allowing rapid access to benzothiophenes, benzofurans, indoles, indolizines, and pyrido[1,2‐a]indoles (see scheme; Tf=trifluoromethanesulfonyl).
快速访问:标题反应生成高度官能化的苯并环杂环和杂二芳基。该方法适用于各种各样的杂芳族化合物,因此可以快速接触苯并噻吩,苯并呋喃,吲哚,吲哚嗪和吡啶并[1,2- a ]吲哚(参见方案; Tf =三氟甲磺酰基)。
