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.
