Substituted benzo-fused heterocycles such as indoles, benzofurans, and a benzopyran were obtained using an intramolecular cross-coupling of vinyl halides with phenols. This transformation represents a new route to these heterocycles and is accomplished using a palladacyclic catalyst under anionic conditions. © 1997 Elsevier Science Ltd.
使用卤代乙烯与酚的分子内交叉偶联获得取代的苯并稠合的杂环,例如吲哚,苯并呋喃和苯并吡喃。该转化代表了通往这些杂环的新途径,并且是在阴离子条件下使用钯环催化剂完成的。©1997爱思唯尔科学有限公司。
