- 中文摘要: The reaction of 3-amino-4, 6-dimethyl-2-thieno[2,3-b]pyridine carbohydrazide (1) with appropriate chalcones 2a-2d in the presence of acid catalyst produced the corresponding 3-amino-2-[(3,5-disubstituted-pyrazolin-l-yl)carbonyl]-4,6-dimethylthieno[2, 3-b]pyridines 3a-3d. 3-Amino-2-[(3-substituted-pyrazolin-l-yl)carbonyl]-4,6-di-methylthieno[2,3-b]pyridines 7a, 7b were also obtained by the cyclization reaction of carbohydrazide 1 with Mannich base derivatives 6a,6b under basic condition.
