Different furans containing an ynamide or alkynyl ether moiety in the side chain were prepared. The gold-catalyzed transformation of these compounds delivered dihydroindole, dihydrobenzofuran, chroman, and tetrahydroquinoline derivatives at room temperature through very fast reactions. Furthermore, the stabilizing effect of the heteroatom directly attached to the intermediate arene oxides led to highly
制备了在侧链中含有乙酰胺或炔基醚部分的不同呋喃。这些化合物的金催化转化在室温下通过非常快速的反应传递了二氢吲哚,二氢苯并呋喃,苯并二氢吡喃和四氢喹啉衍生物。此外,即使仅在单取代的呋喃的情况下,直接连接到中间芳烃氧化物上的杂原子的稳定作用也导致高度选择性的反应,这与以前用非杂原子取代的炔烃获得的结果完全不同。
