one/xanthenedione heterocyclic hybrids have been synthesized via 1,3-dipolar coupling reaction of N/O-substituted-acridinedione-alkyne or O-substituted-xanthenedione-alkyne substrates with various aromatic azides or oximes. In all cases, the cycloaddition is totally regioselective. The chemical structures of the synthesized compounds are determined using 2D NMR and are further confirmed by single-crystal
摘要 通过 N/O-取代-吖啶二酮-炔烃的 1,3-偶极偶联反应合成了一系列新的 1,2,3-三唑-吖啶二酮/呫吨二酮和 1,2-异恶唑-吖啶二酮/呫吨二酮杂环杂化物。或 O-取代的呫吨二酮-炔底物与各种芳族叠氮化物或肟。在所有情况下,环加成是完全区域选择性的。合成化合物的化学结构使用 2D NMR 确定,并通过单晶 X 射线衍射分析进一步确认。对一些选定的化合物进行了两种人乳腺癌细胞系 (MDA-MB-231、T47-D) 和一种前列腺癌细胞系 (PC3) 的初步体外细胞毒性测定。最活跃的 O-1,2,
