Mn(OAc)3-mediated regioselective α′-allylation of α,β-unsaturated enones is described. α′-Allyl α,β-unsaturated enones are obtained through a radical process in good yields.

An efficient rhodium-catalyzed protocol for the synthesis of cyclopentenones based on a three-component reaction of acrylic acids, formaldehyde, and malonates via vinylic C-H activation is reported. Exploratory studies showed that 5-alkylation of as-prepared cyclopentenones could be realized smoothly by the treatment of a variety of alkyl halides with a Na2CO3/MeOH solution. Excess formaldehyde and malonate led to a multicomponent reaction that afforded the multisubstituted cyclopentenones through a Michael addition.
Mn(III)-based C-C bond formation: Regioselective α′-allylation of various α,β-unsaturated, α and β-alkoxy α,β-unsaturated ketones

The Manganese(III)-based regioselective α′-keto radical generation of unsaturated ketones is a versatile synthetic procedure with broad applicability. The generated α′-keto radical slowly creates a metal enolate in a solvent at reflux. The resultant metal
