Trimethylsilyl enol ethers 5, derived from aldehydes or ketones, react with alkyl 1-chloro-2-arylthioalkyl ethers 3 (β-arylthio-α-chloroethers, prepared in situ from vinyl ethers 1 and arenesulfenyl chlorides 2) to give the 2-alkoxy-3-arylthioalkyl ketone derivatives 6 in the presence of a Lewis acid.
从醛或酮衍生的三甲硅基烯醇醚5与烷基1-氯-2-芳硫基烷基醚3(β-芳硫基-α-氯代醚,由乙烯基醚1和芳磺酰氯2原位制备)在路易斯酸存在下反应,生成2-烷氧基-3-芳硫基烷基酮衍生物6。
