Abstract

In this work, a selective synthetic strategy towards 1-azaspiro[4.5]deca-3,6,9-trien-8-ones from -tosyl--(prop-2-yn-1-yl)aniline is developed. The transformation proceeds smoothly in a mixed solvent including acetonitrile and water when ZnBr and Oxone are employed. Mechanism studies show that the reaction proceeds in a regioselective manner a radical -cyclization pathway.
