合成了具有潜在生物活性的二氟亚甲基取代的Goniodiol类似物. 该合成路线的关键步骤为: 铟粉引发对醛的二氟炔丙基化反应引入二氟亚甲基; 在2,2,6,6-四甲基-1-氧基哌啶(TEMPO)催化下, 三氯异氰尿酸(TCCA)氧化1,5-二醇高效率地关环生成α,β-不饱和-δ-内脂环.

关键词: goniodiol, 苯乙烯内酯, α,β-不饱和-δ-内脂环, 二氟亚甲基取代物

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
