An efficient and general route to gem-difluoromethylenated goniodiol has been developed. The in-troduction of a gem-difluoromethylene group was achieved by indium-mediated difluoropropargylation of aldehyde. The α,β-unsaturated-δ-lactone was successfully formed by the oxidation of 1,5-diols in the presence of catalytic 2,2,6,6-tetramethyl-1-piperidinyloxy (TEMPO) and excess trichloroisocyanuric acid (TCCA).

Key words: styryllactone, goniodiol, α,β-unsaturated-δ-lactone, gem-difluoromethylenated compounds
