Mn(III)-based oxidative free-radical cyclization of unsaturated ketones is a versatile synthetic procedure with broad applicability. For example, oxidation of cyclopentanone 1a with 2 equiv of Mn(OAc)3·2H2O and 1 equiv of Cu(OAc)sub
Cyclizations of unsaturated CR(COX)2 radicals. Manganese(III) acetate oxidative cyclizations of unsaturated acetoacetates and atom-transfer cyclizations of unsaturated haloacetoacetates give the same radicals

Comparable regio- and stereochemical results were obtained when cyclizations of a series of 2-substituted 3-oxohept-6-enoate (or oct-7-enoate) esters (acetoacetates) were conducted by manganese(III) acetate oxidation or by iodine or bromine atom transfer
Manganese(III)-Based Oxidative Free-Radical Cyclization of Unsaturated β-Keto Esters, 1,3-Diketones, and Malonate Diesters

Oxidative free-radical cyclizations of unsaturated β-keto esters, 1,3-diketones, and malonate diesters with 2 equiv of Mn(OAc)3*2H2O and 1 equiv of Cu(OAc)2*H2O are described.Oxidation of β-keto ester 1 with Mn(III) to enol radical 2 followed by 6-exo cyc
MANGANESE (III) BASED OXIDATIVE FREE-RADICAL CYCLIZATIONS. 3. POLYCYCLIZATION REACTIONS PROCEEDING THROUGH SECONDARY RADICALS.
Mohan, Raju,Kates, Steven A.,Dombroski, Mark A.,Snider, Barry B.
, p. 845 - 848 (2007/10/02)
Oxidative cyclization 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.
