A successful synthesis of pterocarpans 1, based on a ''disfavored'' 5-endo-trig radical cyclization reaction, has been accomplished. The radical precursor 4-(2Ј-bromoaryloxy)-2Hchromene 8 was synthesized in six steps, starting from aryl propynyl ether 2. On treatment with tributyltin hydride in refl
