A highly regioselective cascade synthesis of 2,3-dihydrobenzodioxepinone from 2-bromophenols and epoxides has been developed. The reactions go through nucleophilic ring-opening of epoxides and subsequent palladium-catalyzed intramolecular alkoxylcarbonylation.
已经开发了由2-溴酚和环氧化物高度区域选择性的级联合成2,3-二氢苯并二恶戊酮。反应通过环氧化物的亲核开环和随后的钯催化的分子内烷氧基羰基化来进行。
