The essential features of the enantiocontrolled total synthesis of (−)-aspicilin are the strategic use of the photochemical rearrangement of α,β-epoxy diazomethyl ketones to 4-hydroxyalkenoates (Scheme 1) and the stereochemical control of the Sharpless epoxidation, α,ω functionalization of an alkynol using potassium 3-aminopropylamine (KAPA) as acetylene zipper, coupling between C7 and C8 by means
对映体全合成(-)-阿斯匹西林的基本特征是对α,β-环氧重氮甲基酮进行光化学重排成4-羟基链烯酸酯的策略性应用(方案1)和Sharpless环氧化α,ω的立体化学控制使用3-氨基丙胺钾(KAPA)作为乙炔拉链对炔醇进行官能化,通过Wittig反应在C 7和C 8之间偶联以及通过使用2,6-二氯苯甲酰氯进行内酯化。
