摘要：
A synthetic application of the rate difference in oxidation of regioisomerically substituted N-acyldihydropyridines is reported. This has allowed for isolation of pure 4-substituted pyridine isomers without the need for chromatography. Diels-Alder adducts between a dihydropyridine and DDQ were isolated and formation of novel hydroquinone ethers was also observed during some reactions.
