Palladium/photoredox catalysis for a decarboxylative radical C(sp 3 )–C(sp 3 ) cross-coupling reaction of γ-methylidene-δ-valerolactones with alkyl carboxylic acids

A radical decarboxylative Csp 3 –Csp 3 cross-coupling of γ-methylidene-δ-valerolactones and non-preactivated alkyl carboxylic acids was developed by combining photocatalysis and palladium catalysis.
