Abstract
Installing a fluoroalkyl group onto the nitrogen atom of azoles represents a potential strategy for lead optimization in medicinal chemistry. Herein, we describe a method for the N-trifluoropropylation of azoles. This process is accomplished using a combination of regioselective N-vinylation and sequential hydrogenation. The two-step sequence is applicable to a diverse set of azoles and tolerates a wide range of functionalities. In addition, we showcase its practicability and utility through the gram-scale synthesis and the late-stage modification of a complex molecule.

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.
