4-benzoquinone imine reacted with enamines to give 1,4-addition products and products of their subsequent cyclization, substituted 5-aminobenzofurans and 5-aminoindoles, depending on the solvent nature, electron-withdrawing power of the substituent on the quinone imine nitrogen atom, and enamine structure. The presence of strong electron-withdrawing trifluoromethanesulfonyl group on the quinone imine nitrogen
1,4-苯醌亚胺的N-磺酰基衍生物与烯胺反应,生成1,4-加成产物及其后续环化产物,取代的5-氨基苯并呋喃和5-氨基吲哚,这取决于溶剂的性质,吸电子能力。醌亚胺氮原子上的取代基和烯胺结构。醌亚胺氮原子上存在强吸电子三氟甲磺酰基,有助于形成1,4-加成产物和苯并呋喃衍生物。
