4-rearrangement in refluxing toluene to give an enol ether , while rearrangement of 2-phenyl derivative proceeded intramolecularly in refluxing xylene to afford a 1,4-rearranged enol ether . On the other hand, ylides were refluxed in alcohols to afford some ring-opened products .
1-苯甲酰基-2-甲基1-3,4-二氢-2-噻吩萘()在回流的甲苯中进行了新的1,4-分子间重排反应,生成烯醇醚,而2-苯基衍生物的重排在回流的二甲苯中进行了分子内反应,得到了烯醇醚。一种1,4重排的烯醇醚。另一方面,将内酯在醇中回流,得到一些开环产物。
