Unexpected Smiles! An unusual and highly regioselective synthesis of dibenzoxazepinones by a domino sequence assisted by an unexpected Smiles rearrangement is reported. The process is effective on electronically differentiated phenols and shows a high tolerance to variation in the benzamide substituents. A plausible path for the reaction, supported by preliminary mechanistic data, is offered.
意外的笑容!据报道,由多米诺骨牌序列在意外的笑容重排的辅助下,对苯并恶唑酮类化合物进行了异常且高度区域选择性的合成。该方法对电子分化的酚有效,并且对苯甲酰胺取代基的变化表现出高度的耐受性。提供了初步的力学数据支持的合理的反应路径。
