Abstract
Hexamethylene tetramine (HMTA) on reaction with beta-diketo compounds (ethyl acetoacetate, acetylacetone and dimedone) yielded corresponding dihydropyridine derivatives in tile aqueous medium. The formation of these tautomeric analogues has been established on the basis of spectr oscopic and chromatographic evidence.
