METAL COMPLEX-CATALYZED SYNTHESIS OF DIHYDROTHIAPYRANS FROM DIALKYL SULFOXIDES AND 1,3-DIENES

A preparative method has been developed for the synthesis of dihydrothiapyrans from dialkyl sulfoxides and 1,3-dienes, catalyzed by palladium and nickel complexes.The scope of this reaction has been assessed, and a mechanism proposed, using 1,3-dienes and sulfoxides of varying structure. Keywords: synthesis, dihydrothiapyrans, catalysts, mechanism, sulfides, 1,3-dienes.

SYNTHETIC USEFULNESS OF SILYL THIOKETONES: FUNCTIONALIZATION OF THEIR PRIMARY ADDUCTS THROUGH DESILYLATION AND TRAPPING BY CARBON ELECTROPHILES.

Desilylation of either α-silyl sulphides or silyl dihydrothiopyrans (easily obtained from silyl thiones as primary adducts), when performed in the presence of carbon electrophiles (aldehydes or ketones), offers an easy entry to carbofunctionalised products.
