Abstract1,3-Benzodioxoles, 1,4-benzodioxanes, and 1,5-benzodioxepanes are flavone analogs that hydroxylamine recyclizes into derivatives of 5-(2-hydroxyphenyl)isoxazoles. They react with thioderivatives with retention of the pyrone ring and formation of oximes. Their structures are proven using PMR spectra.
摘要 1,3-苯并二恶唑、1,4-苯并二恶烷和 1,5-苯并二恶烷是黄酮类似物,羟胺可将其再循环为 5-(2-羟苯基)异恶唑的衍生物。它们与硫代衍生物反应,保留吡喃酮环并形成肟。使用 PMR 光谱证明了它们的结构。
