An intramolecular Huisgen cycloaddition of an interconverting set of isomeric allylicazides with alkynes affords substituted triazoles in high yield. The stereoisomeric vinyl-substituted triazoloxazines formed depend on the rate of cycloaddition of the different allylicazide precursors when the reaction is carried out under thermal conditions. In contrast, dimerized macrocyclic products were obtained
