method for the one-pot synthesis of unsymmetrical 2,5-disubstituted 1,3,4-oxadiazoles has been developed using trichloroisocyanuric acid (TCCA) at ambient temperature. A wide variety of aromatic as well as heterocyclic aldehydes exhibit condensation with a variety of acylhydrazines followed by oxidative cyclization to yield corresponding unsymmetrical 2,5-disubstituted 1,3,4-oxadiazoles. The mild nature
摘要 使用三氯异氰脲酸 (TCCA) 在环境温度下开发了一种一锅法合成不对称 2,5-二取代 1,3,4-恶二唑的有效方法。多种芳香族和杂环醛与多种酰基肼缩合,然后氧化环化产生相应的不对称 2,5-二取代 1,3,4-恶二唑。合成的温和性质和较短的反应时间是所开发协议的显着优势。
