4-dinitrophenyltetrazoles as latent activeesters (LAEs) in the synthesis of amide bonds. Activating the tetrazole generates an HOBt-type activeester 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
