Cycloaddition reactions of 4-sulfur-substituted dihydro-2-pyridones and 2-pyridones with conjugated dienes

Cycloaddition reactions of sulfoxide- and sulfone-substituted dihydro-2-pyridones and 2-pyridones with electron-rich dienes gave new bicyclic and tricyclic products in good to fair yields. The reactivity, regioselectivity, and stereoselectivity of these r

Synthesis and applications of tetrahydro-2-pyridinones via aza-Diels - Alder reactions of thio-substituted 1,3-dienes with arylsulfonyl isocyanates

The first aza-Diels - Alder reactions of arylsulfonyl isocyanates with thio-substituted 1,3-dienes via the 3-sulfolene precursors 1 gave the cyclized products 3 with complete control of chemo- and regioselectivity. The cyclized products 3a and 5 underwent further reactions with nucleophiles and bases to give useful heterocyclic compounds. The N-tosyl group of the cyclic products could be selectively replaced by hydrogen or another substituent.

Aza-Diels-Alder reactions and synthetic applications of thio-substituted 1,3-dienes with arylsulfonyl isocyanates

The first aza-Diels-Alder reactions of arylsulfonyl isocyanates with thio-substituted 1,3-dienes via the 3-sulfolene precursors 1 gave the cyclized products 3 with complete control of regio- and chemoselectivity. The cyclized products 3a and 4 underwent further interesting reactions with nucleophiles and bases to give useful heterocyclic compounds. (C) 2000 Elsevier Science Ltd.
