The Mukaiyama-Michael Reaction of N-Acyl-2,3-dihydro-4-pyridones: Regio- and Stereoselective Synthesis of cis-2,6-Disubstituted 1,2,5,6-Tetrahydropyridines
摘要:
[GRAPHICS]A convenient regio- and stereoselective preparation of 1,2,5,6-tetrahydropyridines of the type 1 has been developed, starting from readily available N-acyl-2,2-dihydro-4-pyridones 2.

as its vinyltriflate (3). This enolate interconversion is dependent on the dihydropyridone C-2 substituent and can be interpreted in terms of conformational analysis. This novel scaffold (3) opens another avenue for the strategic deployment of dihydropyridones into both natural product synthesis and drug discovery. To this end, this method is highlighted by its use as a key step in a total synthesis
