A new approach to pyridines through the reactions of methyl ketones with 1,2,4-triazines?
RSC Advances Pub Date: 2014-10-29 DOI: 10.1039/C4RA11294F
Abstract
A new route to prepare pyridine derivatives based on inverse electron demand Diels–Alder/retro-Diels–Alder reactions of ketones with 1,2,4-triazines is reported. It is the first time using methyl ketones directly as a dienophile to react with 1,2,4-triazines without enamine intermediates, which is complementary to the classical Boger reaction.
