Abstract

Oxidation Cyclizations Chemical Sciences
Oxidative cyclizations of 3, 14, 18 and 21 with Mn(OAc)3 ·2H2O give the tricyclic products 6, 15, 19 and 23, respectively, in good yield. These reactions proceed through a monocyclic secondary radical which adds to the benzene ring prior to the second oxidation.
