Mn(III)-promoted synthesis of functionalized γ-lactones in acetic and formic acids

Article abstract of DOI:10.1016/S0040-4039(98)01890-5

The yield of substituted γ-lactones obtained by Mn(III)-mediated addition of potassium monomethyl malonate on cinnamate esters can be optimized by performing the reaction either in acetic or in formic acid, depending on the substrate.
