An unprecedented approach involving radical-mediated sulfonylation/dearomative ipso-annulation of N-(methyl-2-phenylacetate)propiolamides using arylsulfonyl radical, generated from aryl diazonium salt in the presence DABSO, is developed. This strategy provides uniquely substituted 3-sulfonyl azaspiro[4.5]decatrienones good yields. The developed has also been extended fruitfully to 3-thiocyano aza-spirocycles through domino thiocyanation/dearomative ipso-annulation.

Abstract Herein, we present an efficient strategy for the synthesis of spiro(indenyl)cyclohexadienones through radical‐promoted reaction 2‐alkynyl biaryls with sodium sulfinates under electrochemical conditions. The involves sulfonylation and dearomative ipso‐ cyclisation in a domino fashion. This approach features use readily accessible precursors, wide functional group tolerance external oxidant‐free practicality method was also illustrated by scale‐up further diversification product.
