Mn(III)-based oxidative free-radical cyclizations of unsaturated ketones
McCarthy Cole, Bridget,Han, Luning,Snider, Barry B.
, p. 7832 - 7847 (2007/10/03)
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
Kates, Steven A.,Dombroski, Mark A.,Snider, Barry B.
