A unique two-carbon ring expansion of isatin has been achieved to conveniently construct the functionalized dibenzo[b,d]azepin-6-one scaffold in moderate to high yields, and the two carbon sources are different: one carbon is from the N-substituent of pyridinium bromide and the other is from indene-1,3-dione.
实现了异吲哚酮独特的双碳环扩展，以中等至高收率方便地构建功能化的二苯并[b,d]氮杂䓬-6-酮骨架，且两个碳源不同：一个碳来自溴化吡啶鎓的N-取代基，另一个碳来自茚-1,3-二酮。
