REACTION SEQUENCE ARYLSULFENYL CHLORIDE + ALKOXYALKENE-I + ALKOXYALKENE-II + ALLYLMAGNESIUM OR BORON DERIVATIVES AS A NEW METHOD FOR THE CONTROLLED SYNTHESIS OF POLYFUNCTIONAL DERIVATIVES

Article abstract of DOI:10.1007/BF00961360

A new method is proposed for the controlled synthesis of polyfunctional compouds 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.
