An improved method for the introduction of carbon-carbon triple bond at C-13 in PG-synthesis is described. The efficient aldol reaction of aldehydes has been achieved by using α-chloro enolate anions derived from 1-bromo-1-chloro ketones, giving α-chloro enones after dehydration in good yields, the precursor of the acetylenic alcohols.
描述了一种在PG合成中在C-13处引入碳-碳三键的改进方法。通过使用衍生自1-溴-1-氯酮的α-氯烯酸根阴离子,可以实现醛的有效醛醇缩合反应,脱水后,乙炔醇的前体可得到高产率的α-氯烯酮。
