Abstract
A zinc bromide-catalyzed synthesis of 5-substituted tetrazoles via DNA-conjugated nitriles using sodium azide has been developed. The protocol offered moderate to excellent yields of tetrazoles with a broad range of substrates, including a variety of functionalized aromatic, heterocyclic, and aliphatic nitriles. In addition, the electronic effect within the substrate scope was evaluated. DNA fidelity was assessed by ligation efficiency and amplifiability analysis. The ability to generate tetrazoles expands the diversity of heterocycles in the preparation of DNA-encoded chemical libraries.
