A liquid-phase traceless route to 3,5-disubstituted-1,2,4-triazoles has been developed, which allows for the incorporation of two elements of diversity. The heterocycle was constructed upon PEG6000 (soluble polymer) modified by 4-hydroxy-2-methoxybenzaldehyde, from which a traceless cleavage could be realized with TFA-CH2Cl2. This method provided a library of 3,5-disubstituted-1,2,4-triazoles with high yields and purity.
我们开发出了一种液相无痕制备 3,5-二取代-1,2,4-三唑的方法,这种方法可以加入两种多样性元素。杂环由经 4-羟基-2-甲氧基苯甲醛修饰的 PEG6000(可溶性聚合物)构建而成,并可通过 TFA-CH2Cl2 实现无痕裂解。这种方法提供了一个高产率和高纯度的 3,5 二甲基-1,2,4-三唑化合物库。
