A copper-catalysed one-pot hydroboration/azidation/cycloaddition reaction of alkynes†
Herein we report our study on the development of a catalytic one-pot process, showing the challenges and advantages encountered all over the way. At the end, we developed a regioselective, environmentally friendly, and operationally simple method to explore the reactivity of functionalized propargylic alkynes through three copper-catalysed reactions in a single reaction vessel. The sequence consisted of a hydroboration, azidation, and 1,3-dipolar cycloaddition and led to the regioselective formation of vinyl 1,2,3-triazoles in good yields.
