A prostacyclin analogue, dl-3-oxa-9 (Ο)-methano-Δ6 (9α) -prostaglandin I1 (1a), has been synthesized. The key step for this synthesis is a new, one-step conversion reaction of the (hydroxymethyl) cyclopropylketone group in 8 and 21 to the γ, δ-unsaturated ketone 9 and 22, respectively, with iodotrimethylsilane.
合成了一种前列腺素类药物类似物,dl-3-氧杂-9 (Ο)-甲基-Δ6 (9α) -前列腺素I1 (1a)。该合成的关键步骤是将8和21中的(氢氧基甲基)环丙基酮基团通过碘三甲基硅烷进行一次性转化反应,得到γ, δ-不饱和酮9和22。
