摘要

Thermal cyclization of l-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 corresponding aromatic anions which can be alkylated with methyl iodide or acylated with ethyl chloroformate.
