ChemInform Abstract: ALKYLATION OF SILYL ENOL ETHERS BY EPISULFONIUM SALTS AND β-HALOALKYL ARYL SULFIDES - METHOD FOR THE INTRODUCTION OF THE β-ARYLTHIOALKYL GROUP INTO CARBONYL COMPOUNDS

1. The reaction of β-haloalkyl aryl sulfides or episulfonium salts with the trimethylsilyl ethers of enols is a general method for the introduction of the β-arylthioalkyl group into carbonyl compounds. 2. The opening of the episulfonium ring in this reaction is regioselective and stereospecific. 3. The reaction permits the synthesis of polyfunctional compounds from simple alkene and carbonyl compound precursors.
