A BF<sub>3</sub>-Mediated Nitrogen-to-Carbon Rearrangement of N-Protected 2,3-Dihydro-3-hydroxy-1<i>H</i>-benzisoindol-1-ones, and Its Interception for a Facile Preparation of 3-Substituted Benzisoindolones

accompanied by recombination of the nitrogen-protecting unit to the 3-position of the ring system. The addition of sulfur or carbon nucleophiles affords products of preferential capture of the rearrangement intermediate offering a convenient and rapid synthetic route to N-unprotected 2,3-dihydro-3-substituted-1H-benzisoindol-1-ones.
BF 3 介导的 N-(枯基或 1,1-二苯基乙基)-2,3-二氢-3-羟基-1H-苯并异吲哚-1-酮的羟基和氮保护基团的释放伴随着将氮保护单元连接到环系统的 3 位。硫或碳亲核试剂的添加提供了重排中间体的优先捕获产物,为 N-未保护的 2,3-二氢-3-取代-1H-苯并异吲哚-1-酮提供了方便快捷的合成途径。
