A novel and mildmethod was established to synthesize 6-methylidene penem compounds. This method entails a MgBr2/Et3N-promoted aldol-type condensation on 6-bromopenem 12 with an appropriately substituted aldehyde to yield the intermediate acetylated bromohydrin, which was smoothly converted to the final product with simultaneous deprotection of C3 carboxylic acid ester using activated zinc dust and
建立了一种新颖且温和的方法来合成6-亚甲基青霉烯化合物。该方法需要在6-溴openem 12上用适当取代的醛在M- Br 2 / Et 3 N上促进的Aldol型缩合反应,生成中间体乙酰化的溴代醇,将其平滑地转化为最终产物,同时使用C3羧酸酯进行脱保护pH 6.5的活性锌粉尘和磷酸盐缓冲液。该方法为青霉素衍生物的CC键形成方法提供了有用的变化,并且还用作制备6-外亚甲基青霉烯衍生物而在C5位不消旋的实用合成方法。
