Article abstract of DOI:10.1021/jo00289a034

Thermal cyclization of 1-azido-2-penten-4-ynes and 4-azido-2-butenenitriles led to 6H-pyrrolo<1,2-c><1,2,3>triazoles and 5H-pyrrolo<1,2-d>tetrazoles, respectively, in good yields.Upon treatment with methyllithium these heterocyclic compounds gave the corr
