Methyl-3-oxo-5'-(2',6',6'-trimethylcyclohex-2'-enyl and l'-enyl) pentanoates 1a and 1b were submitted to both: Lewis acid (tin (IV) tetrachloride) and free radical (manganese (III) acetate) cyclization conditions. The structures of the different products are discussed in terms of the reaction mechanisms.
