Abstract

New symmetrical 4-[2-chloro-2-(4-chloro-6-methyl-2-oxo-2H-pyran-3-yl)vinyl]-substituted 1,4-dihydropyridines were synthesized in moderate to good yields via modified Hantzsch reaction of β-dicarbonyl compounds with (Z)-3-chloro-3-(4-chloro-6-methyl-2-oxo-2H-pyran-3-yl)acrolein in the presence of excess amount of NH4OAc. Also reaction of β-dicarbonyl compounds with (Z)-3-chloro-3-(4-chloro-6-methyl-2-oxo- 2H-pyran-3-yl)acrolein in the presence of enamino esters and ketones was performed and asymmetrical 4-[2-chloro-2-(4-chloro-6-methyl-2-oxo-2H-pyran-3-yl)vinyl]-substituted 1,4-dihydropyridines were obtained in moderate to good yields at room temperature. The calcium channel blocking activity of these compounds were assessed in which they demonstrated moderate to weak effects, although, one compound had a comparable effect (IC50 =1.40×10-7 M) regarding to reference drug, Nifedipine.
