4-dinitrophenyltetrazoles as latent active esters (LAEs) in the synthesis of amide bonds. Activating the tetrazole generates an HOBt-type active ester without the requirement for exogenous coupling agents. The methodology was widely applicable to a range of substrates, with up to quantitative yields obtained. The versatility and functional group tolerance were exemplified with the one-step synthesis of various pharmaceutical
我们报告了在酰胺键合成中使用N -2,4-二硝基苯基四唑作为潜在活性酯 (LAE)。激活四唑可生成 HOBt 型活性酯,无需外源偶联剂。该方法广泛适用于一系列底物,获得了高达定量的产量。多功能性和官能团耐受性通过各种药剂的一步合成和树脂结合肽的N-酰化来举例说明。
