Fluoroalkyl 1,2,3-triazoles have great potential as medicinal chemistry building blocks. However, only a few synthetic routes to these compounds are currently available. Herein, we report on a novel method to access 5-fluoroalkyl 1,2,3-triazoles from easily prepared bench-stable perfluoroalkyl N-mesylhydrazone (PFHZ-Ms), a reagent that can transform amines to 5 fluoroalkyl 1,2,3-triazoles via defluorinative [4 + 1] annulation. The simple reaction protocol can be applied to a variety of amines containing a range of functional groups, delivering 1,2,3-triazoles in good to excellent yield. The utility of this method was demonstrated in the late-stage modification of bioactive molecules.

Abstract

Fluoroalkyl 1,2,3-triazoles have great potential as medicinal chemistry building blocks. However, only a few synthetic routes to these compounds are currently available. Herein, we report on a novel method to access 5-fluoroalkyl 1,2,3-triazoles from easily prepared bench-stable perfluoroalkyl N-mesylhydrazone (PFHZ-Ms), a reagent that can transform amines to 5 fluoroalkyl 1,2,3-triazoles via defluorinative [4 + 1] annulation. The simple reaction protocol can be applied to a variety of amines containing a range of functional groups, delivering 1,2,3-triazoles in good to excellent yield. The utility of this method was demonstrated in the late-stage modification of bioactive molecules.
