intramolecular didehydro-Diels–Alder reaction, ene–yne substituted pyrroles, thiophenes, and furans afford functionalized indoles, benzothiophenes, and benzofurans and the corresponding dihydroaromatic products. Product selectivity for the aromatic or dihydroaromatic product is controlled by the reaction conditions, which vary depending upon the substrate.
使用分子内的双氢-狄尔斯-阿尔德反应,烯-炔取代的吡咯,噻吩和呋喃提供官能化的吲哚,苯并噻吩和苯并呋喃及相应的二氢芳族化合物。芳族或二氢芳族产物的产物选择性由反应条件控制,反应条件根据底物而变化。
