e heterocyclic hybrids has been efficiently synthesized via a one-pot catalyst-free three-component reaction of α-bromoacetylated pyran-2-one derivatives, thiosemicarbazide, and polysubstituted-1-(1H-pyrazol-4-yl)butane-1,3-diones. This multicomponent procedure has been advantageously applied to prepare a structural diversity of heterocyclic hybrids characterized by extensive 1D and 2D NMR spectroscopic
通过 α-溴乙酰化 pyran-2-one 衍生物、氨基硫脲和多取代-1 的一锅无催化剂三组分反应,有效合成了一系列新的有趣的双吡唑-噻唑-吡喃-2-one 杂环杂化物-(1H-pyrazol-4-yl)butane-1,3-diones。这种多组分程序已被有利地应用于制备以广泛的 1D 和 2D NMR 光谱研究为特征的杂环杂化物的结构多样性。
