Abstract
A synthetic application of the rate difference in oxidation of regioisomeri cally substituted N-acyldihydropyridines is reported. This has allowed for isolation of pure 4-substituted pyridine isomers without the need for chrom atography. Diels-Alder adducts between a dihydropyridine and DDQ were isola ted and formation of novel hydroquinone ethers was also observed during som e reactions.
