Abstract
Abstract: Hantzsch condensation of two equivalents of methyl-3-aminocrotonate with (m-and p)-methoxybenzaldehyde afforded the expected products 2, 6-dimethyl-3, 5- dimethoxycarbonyl-4-(m-methoxyphenyl)-1, 4-dihydropyridine and 2, 6-dimethyl-3, 5- dimethoxycarbonyl-4-(p-methoxyphenyl)-1, 4-dihydropyridine, whereas o-methoxy- benzaldehyde produced mainly 1-amino-2-methoxycarbonyl-3, 5-bis (o-methoxy-phenyl)- ...
