nitromethane conjugate addition to 2-cyclo-pentenones bearing a 4-oxygenated function has been illustrated through a short and practical synthesis of the Corey aldehyde, a key intermediate in prostaglandin synthesis, in both racemic and optically active form. A new synthesis of PGF2α featuring the introduction of the ω-chain via [3+2] cycloaddition has been also described.
通过短而实用的外消旋和旋光形式合成Corey醛(Cores醛是前列腺素合成的关键中间体),说明了硝基甲烷共轭物加成物与带有4-氧合功能的2-环戊烯酮的相容性。PGF的新合成2α设有经由[3 + 2]环加成已经描述也引入ω链的。
