Direct preparation of 2-amino-5,6,7,8-tetrahydro-4-(4-methoxyphenyl)-7,7-dimethyl-5-oxo-4H-chromene-3-
carbonitrile (2) and 1,2-diamino-1,4,5,6,7,8-hexahydro-4-(4-methoxyphenyl)-7,7-dimethyl-5-oxo-3-quinolinecarbonitrile
(11) which were utilized as starting products for the synthesis of S-nucleoside analogues of kinds 10, 15 and C-nucleoside
analogues of types 12, 13 is presented in the current study. The antibacterial and antifungal activities of these new compounds
were evaluated. The structures of the new products were confirmed on the basis of elemental and spectral analysis
Keywords: Chromeno[2, 3-b]pyridines, [1, 2, 4]triazolo[1, 5-a]quinolines, L-rhamnopyranosyl bromide, antimicrobial activity.
