Condensation Reactions of 2-Acetylpyridine and Benzaldehydes: New Cyclohexanol Products and an Improved Synthesis of 4′-p-Tolyl-2,2′:6′,2″-terpyridine
Abstract
Condensations of 2-acetylpyridine with p-tolualdehyde and 4-tert-butylbenzaldehyde furnish three new cyclohexanol 3:2 condensates (3d,e and 7), including a new diastereomer, and open a better route to 4′-p-tolyl-2,2′:6′,2″-terpyridine (1b) via the new 2:1 condensate, 1,5-di(2-pyridyl)-3(4-methylphenyl)pentane-1,5-dione (6).
