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.

Trimethylsilyl and DBU nitronates derivedfrom nitromethane and nitropropanes do not undergoC-alkylation by episulfonium (ESI) or thiophanium (TPI) cationic intermediates. The above-mentioned derivatives of 1-nitropropane react with ESI and TPI to give the corresponding products ofO-alkylation of 1-chloro-1-oxyiminopropane. The reactions of DBU nitronates derivedfrom nitromethane and 2-nitropropane

A new method is proposed for the controlled synthesis of polyfunctional compounds with formation of two new carbon-carbon bonds; the method is based on the following reaction sequence, which can be carried out in a single flask: addition of ArSCl to vinyl ether I, reaction of the resultant adduct with vinyl ether II in the presence of Lewis acid to form a cationic complex, and treatment of the latter with allyl derivatives of boron or magnesium.
