Sixteen 2-methyl-3-acetyl-4-aryl-5-oxo-1,4-dihydro-SH- indeno(1,2b)pyridine derivatives (3a-p) have been prepared. The structures of the compounds were characterised by IR, 1H-NMR, 13C-NMI, X-Ray and elemental analyses. The calcium a

The patterns governing the dependence of NH-acidity on the presence of α-, β- and γ-substituents in the 1,4-dihydropyridine ring and on their nature have been established by comparison of the pKa values of monocyclic 1,4-dihydropyridines and 4,
