An efficient and highly diastereoselective synthesis of 2-substituted benzo[b]azepin-5-ol via stereocontrolled addition of Grignard reagents to oxa-bridged benzazepines has been developed. The reaction proceeds efficiently starting from versatile skeletons with mild reaction conditions as well as simple operation. Furthermore, 2-substituted benzazepinones could been obtained by simple Dess–Martin oxidation
已经开发出通过将格氏试剂立体控制地添加到氧杂桥联苯并氮杂来高效且高度非对映选择性地合成 2-取代苯并[ b ]azepin-5-ol 。该反应从具有温和反应条件和简单操作的多功能骨架开始有效地进行。此外,2-取代的苯并氮杂酮可以通过简单的 Dess-Martin 氧化以优异的收率获得。
