Photocatalytic Synthesis of Indene Carbohydrazides via Skeletal Editing of Cyclic α-Diazo Ketones

)-naphthalenones (DNQs) and hydrazines without using any catalyst or additive have been realized for indene carbohydrazide synthesis. This mild and sustainable method allows the synthesis of products with a broad scope based on a key process of skeletal editing in the six-membered cyclic enone moiety of DNQ through Wolff rearrangement. In addition, practical results have been obtained from both batch and continuous flow operations.
