Abstract: A new method for the synthesis of 1, 4-dihydropyridine (1, 4-DHP) calcium channel antagonists felodipine, nitrendipine and their derivatives via papain-catalyzed three-component reactions of aldehyde, methyl acetoacetate and ethyl 3-aminocrotonate was developed. Operational simplicity, mild reaction conditions and eco-friendliness are the key features of this protocol.
