Abstract
Efficient methods for the Michael addition reactions of N-arylsulfonyl -3-phenylthiopiperidones (1) with both the protected amidoacrylates (4 , 9) and the simple acrylates (12) have been developed. These reaction s offer an efficient route to the 3-alkyl-substituted dihydropyridinon es (3, 11), the dienophiles employed in the natural product synthesis.
