Pyridine and triphenylphosphine oxide activation of sulfonyl chlorides in the syntheses of (E) alk-1-enyl sulfones

This paper describes efficient and new approaches to (E) alk-1-enyl sulfones, starting from sulfonyl chloride/pyridine or sulfonyl chloride/triphenylphosphine complexes in the presence of (E) di-iso-butyl alk-1-enyl alanes. The use of CuCl in the presence of sulfonyl chloride/pyridine complexes or pyridine in the presence of sulfonyl chloride/triphenylphosphine complexes, respectively, results in a remarkable increase in the yields and conversions.

Regio- and Stereoselective Synthesis of (E)- and (Z)-Vinylic Sulfones and Their Conversion to the Corresponding Allylic Sulfones

(E)- and (Z)-vinilyc sulfones were prepared regio- and stereoselectively from 1-alkenes or 1-alkynes in high yields via iodosulfonization in AcOEt-H2O.The vinylic sulfones thus prepared were converted to the corresponding allylic sulfones by treatment wit
