6-disubstituted-3(2H)-benzofuranone derivatives. It was found that depending on the reaction conditions, degradation products or the products of oxidation were isolated. This latter reaction became the main process when the ring closure was performed starting from methoxy- or 2-propoxy-desoxybenzoin and diethyl bromo-(or chloro-)-malonate to give d,l- and meso-dimers of the substituted 3(2H)-benzofuranones.
摘要 两种已知方法用于合成 2,6-二取代-3(2H)-苯并呋喃酮衍生物。发现根据反应条件,分离出降解产物或氧化产物。当从甲氧基-或 2-丙氧基-脱氧安息香和溴-(或氯-)-丙二酸二乙酯开始闭环时,后一个反应成为主要过程,得到取代的 3(2H) 的 d,l- 和内消旋二聚体)-苯并呋喃酮。
