A triazole-templated ring-closing metathesis for constructing novel fused and bridged triazoles

The feasibility of trapping the vinyl copper intermediate generated in situ from azide-[3 + 2] cycloadditions and viability of employing these triazoles as unique templates for ring-closing metathesis are described here; this work effectively combines the two powerful reactions for the first time to construct various de novo fused and bridged triazoles that are otherwise not trivial to synthesize.
