pyridazinopyrimidine) and other type fused rings containing pyridazine moiety. For the synthesis of these fused-heterocyclic bases, 6-nitro and 6formylpyridazin-3(2H)-ones are useful. In order to synthesize useful intermediates for some fused pyridazinone and/or new fungicidal agents, we attempted to prepare some 6-nitro-(or amino, hydroxylamino and formyl)pyridazin3(2H)-ones. In this paper, we report the functionalization
自发现吡咯并[2,3-c]哒嗪或吡咯并[2,3-d]哒嗪显示出抗增殖活性和抗病毒活性以来,人们一直在关注开发方便有效的杂环碱基合成方法,例如吡咯并[2,3-c]哒嗪和吡咯并[2,3-d]哒嗪,它们是C4N2-C4N型稠环。为了修饰新的杀菌剂的稠合杂环骨架,我们需要C4N2-C3N(吡咯并哒嗪),C4N2-C3N2(咪唑并哒嗪),C4N2-C4N2(吡啶并哒嗪或哒嗪并嘧啶)和其他含哒嗪部分的稠合环。对于这些稠合杂环碱基的合成,有用6-硝基和6-甲酰基哒嗪-3(2H)-一。为了合成一些稠合的哒嗪酮和/或新的杀菌剂的有用中间体,我们试图制备一些6-硝基-(或氨基,羟氨基和甲酰基)哒嗪3(2H)-ones。在本文中,我们报告了4,5-二氯哒嗪-3(2H)-one和4,5-二氯-2甲基-6-硝基哒嗪-3(2H)-one的功能化。
