The gem-dialkyl effect has been used to promote the formation of functionalized γ-lactones in the addition of benzenesulfonyl bromide to diene and enyne esters. Introduction of 3 tool % of pyridine into the reactions increases the yields of lactones produced from tertiary esters. Formation of the C(α)-C(β) bond of γ-lactones has been achieved in both C(α)→C(β) and Cβ→C(α) radical cyclization directions.
