  SYNTHESIS OF PYRIDAZOTHIENOTHIAZINE AND PYRIMIDOTHIENOPYRIDAZINES

  摘要：

  3-amino-4,5-diphenylthieno[2, 3-c]pyridazine-2-arylcarboxamide 2 underwent cyclization with triethyl orthoformate and with nitrous acid to give the pyrimidothienopyridazines 3a-c, 4b respectively. 3-amino-4,5-diphenylthieno [2,3-c] pyridazine-2-carbohydrazide 6 reacted with aromatic aldehydes to give;the corresponding carbohydrazones 7a-c. Compound 7 reacts with triethyl orthoformate, acetic anhydride or with CS2/pyridine to produce pyrimidothienopyridazines 8,9 and pyridazothienothiazine 11.
