摘要

Abstract The Hantzsch condensation of the heteroarylcarboxaldehydes 3a-c with alkyl acetoacetates 4a-c and alkyl 3-aminocrotonates 5a-b afforded the respective dialkyl 1, 4- dihydro-2, 6-dimethyl-4-(heteroaryl)-pyridine-3, 5-dicarboxylates 6a-f possessing a C-4 4- quinolinyl, 8-quinolinyl or 1-oxido-4-pyridinyl substituent Calcium channel antagonist structure-activity relationships acquired indicate that i) the position of the quinolyl nitrogen ...
