Consecutive 2-azidoallylation/click cycloaddition of active methylene for synthesis of functionalized hepta-1,6-dienes with a bis-1,2,3-triazole scaffold

A tandem 2-azidoallylation/click cycloaddition reaction can be accomplished with methylene compounds, phenolic substituted vinyl azide and alkynes in one pot. This general cascade reaction smoothly enables the construction of novel multifunctional hepta-1,6-dienes bearing quaternary/tertiary carbon and a bis-1,2,3-triazole scaffold in good to excellent yields.
