Silyl enol ethers (1) react with the phenylthio(methoxycarbonyl)alkyl chlorides (2) in the presence of Lewis acids to give good yields of the γ-ketoesters (3); oxidative and reductive desulphurisations give the saturated (4) and unsaturated (5 or 6) γ-keto esters, respectively.
在路易斯酸的存在下,甲硅烷基烯醇醚(1)与苯硫基(甲氧羰基)烷基氯化物(2)反应,得到高产率的γ-酮酸酯(3);氧化和还原脱硫分别得到饱和的(4)和不饱和的(5或6)γ-酮酯。
