New fused tetrazolone derivatives were synthesized using homophthalic and maleic anhydrides. Treatment of anhydrides with trimethylsilyl azide opened the lactone rings and formed the corresponding intermediates, which bore 1,3-dipole and dipolarophile functionalities in ortho positions. The intermediates partially underwent internal 1,3-dipolar cycloaddition to produce fused tetrazolone derivatives. When the carbonyl groups in anhydride were not conjugated with any double bond, then a triazine-fused tetrazolone derivative was formed.
使用均苯二甲酸和马来酸酐合成了新的融合四氮唑酮衍生物。用三甲基硅叠氮化物处理酸酐可打开内酯环并形成相应的中间体,这些中间体在正交位置具有 1,3-偶极和亲偶极官能团。这些中间体部分发生内部 1,3-二极环化反应,生成融合的四唑酮衍生物。当酸酐中的羰基不与任何双键共轭时,就会形成三嗪融合四氮唑酮衍生物。
