We present an experimental and computational study of the reaction of aryl substituted benzyl 1-alkynyl sulfides with potassium alkoxide in acetonitrile, which produces 2-aryl 2,3-dihydrothiophenes in poor to good yields. The cyclization is most effi

Using established and new 1H NMR data for sulfinate esters and sulfinyl chlorides, the parameters required for predicting position-dependent alkene 1H NMR chemical shifts of vinylic sulfinate esters and vinylic sulfinyl chlorides have been obtained.

Enantiomerically enriched α,β-unsaturated sulfinate esters of ()-cholesterol undergo stereospecific substitutions at sulfur when treated in benzene at 6°C with Grignard reagents. Sulfoxides with ees of 8599.5% are obtained when enantiopure sul

A convenient synthesis of leflunomide and its primary pharmacologically active metabolite A77 1726, each labeled with four 13C atoms has been achieved. Starting from 13C4-ethyl acetoacetate, each step of the synthesis proceeds in 60–82% yield. Anal

The electrochemical reduction of benzyl thiocyanate and p-nitrobenzyl thiocyanate was investigated in acetonitrile at an inert electrode. These two compounds reveal a change in the reductive cleavage mechanism, and more interestingly, they show a cle
