Photocatalytic chemo-, regio- & stereoselective olefinic β-C-H decarboxylative alkylation of enamides with diacyl peroxides.

A decarboxylative alkylation of enamides with alkyl diacyl peroxides induced by visible-light is described. The chemo-, regio- and stereoselective olefinic β-C-H alkylation generates a series of primary- and secondary alkylated enamides in yields up to 95%. This transformation bears the advantages of operational simplicity, good functional group compatibility and mild conditions.
