A general preparation of new types of benzofurans, benzothiophenes and indoles is realized via chemoselective intramolecular Wittig reactions with the corresponding ester, thioester and amide functionalities using in situ formed phosphorus ylides as key intermediates. The reaction conditions are very mild, and numerous Michael acceptors and commercially available acid chlorides can be applied very
新型苯并呋喃,苯并噻吩和吲哚的一般制备方法是通过化学选择性分子内Wittig反应,使用原位形成的磷化磷作为主要中间体,与相应的酯,硫酯和酰胺官能团进行的。反应条件非常温和,可以一步一步高效地应用许多迈克尔受体和市售的酰氯。
