4]-Triazolo[3,2-d][1,5]benzoxazepine skeleton was easily achieved by cycloaddition of the allene-like cations 3, derived from 4-chromanone arylhydrazones, to the triple bond of nitriles and ensuing ring enlargement. The structural assignment of one product (5d) has been ultimately accomplished by X-ray diffraction analysis.
摘要 前所未有的 [1,2,4]-三唑并[3,2-d][1,5]苯并恶氮骨架是通过将衍生自 4-色满酮芳腙的类丙二烯阳离子 3 环加成到腈和随之而来的环扩大。一种产品 (5d) 的结构分配最终通过 X 射线衍射分析完成。
