Abstract:Radical cyclization reactions are still a challenging field in synthetic organic chemistry. Herein, the radical reactions of 6‐ and 7‐membered diosphenol derivatives (tropolone) with a significant difference in reactivity, ring size, aromaticity and stability were investigated. While the former produces a mixture of products including oxabicycloalkanones, the experimental work performed herein resulted with a single 2‐(3‐hydroxypropyl)cyclohepta‐2,4,6‐trienone product, regioselectively.
