    摘要: 4-Substituted-1,4-dihydropyridines are prepared by a cycloaddition reaction in which the cyclization is driven to completion, after thermal reaction, by addition of an acid. Felodipine, a vasodilator, is prepared by a cycloaddition reaction of ethyl 3-aminocrotonate with a suitably substituted dichlorobenzylidine under reaction conditions whereby the product crystallizes out of the reaction solution and may be directly isolated by filtration.
