Preparation of an oxetan-phenyltetrahydropyridazine-3,6-dione derivative using some chemistry tools %K steroid %K derivative %K phenylhydrazine %K tetrahydropyridazine %K oxetan %R %X The aim of this study was to synthesize a new oxetan-phenyltetrahydropyridazine-3,6-dione derivative (compound 6) using with different techniques. The first method was achieved by the preparation of a phenylhydrazine derivative (2) using three components system (3,17-aldol-estradiol, phenylhydrazine, 5-hexyn-3-ol) in presence of Copper(II). Then, 2 Was reacted with tert-butyldimethylsilyl chloride to form the compound 3 (trimethylbutan-silyloxy-steroid-hydrazine). Following, a pyridazine derivative (4); was prepared by the reaction of 3 with succinic acid using boric as catalyst. The compound 4 was reacted with hydrofluoric acid to form the a tetrahydropyridazine-3,6-dione (5). Finally, the preparation of 6 was carried out by the reaction of 5 with CopperII. Spectroscopy analyses NMR was used to confirm the chemical structure of compounds. In conclusion, in this study a facile method to synthesis of an oxetan-phenyltetrahydropyridazine-3,6-dione is reported. %U https://icc.journals.pnu.ac.ir/article_4594_7956810b773bf2e8af357e7b71094a1c.pdf
