nicotinaldehydes with aminocrotonoates in the presence of p-TsOH at room temperature. The prepared compounds were evaluated for their anti-microbial, free-radical scavenging and α-glucosidase inhibitory activities. Compounds diethyl 2,6-diphenyl-4-(pyridin-3-yl)-1,4-dihydropyridine-3,5-dicarboxylate and diethyl 4-(2-chloro-5-(4-fluorophenyl)pyridin-3-yl)-2,6-diphenyl-1,4-dihydropyridine-3,5-dicarboxylate were
