radical mechanism, independent of the cyclooxygenase enzymes. These new compounds are available from natural sources only in microgram quantities as mixtures. The enantioselective preparation of two enediol isofurans, 15-epi-ent-SC-Δ13-8-IsoF and ent-SC-Δ13-8-IsoF, is described. A key transformation in the synthesis is the selective cascade cyclization of a diol epoxide benzenesulfonate to give the substituted
异呋喃(IsoF's)是一类新的人类花生四烯酸氧化产物。它们是通过自由基机理在体内产生的,而与环氧化酶无关。这些新化合物只能以微克的量从天然来源以混合物形式获得。2个烯二醇isofurans,15-的对映选择性制备外延-ent-SC-Δ 13 -8- ISOF和ENT-SC-Δ 13 -8- ISOF,进行说明。合成中的关键转变是二醇环氧苯磺酸盐的选择性级联环化反应,生成异呋喃的取代四氢呋喃骨架。这种合成将使这些代谢物可用于生理评估。
