摘要

The synthesis, structural characterization and calcium blocking activity of a series of benzofurazanyl-1, 4-dihydropyridines (18 and 19) and benzofuroxanyl analogues (20 and 21) are reported. 1H-NMR showed that all the benzofuroxan derivatives exist in solution as tautomeric mixtures. The predominant tautomeric form in solution of the derivative 20 (dimethyl 1, 4-dihydro-2, 6-dimethyl-4-(4-benzofuroxanyl)-3, 5-pyridinedicarboxylate) is ...
