摘要
[image omitted] The synthesis of a small series of fused tricyclic 1,2,4-triazoles is described. The key reaction is an intramolecular two-stage, one-pot reduction/cyclization sequence of a nitropyridine/oxadiazole substrate to give the key tricyclic triazole. Further standard transformations convert this template into a series of final target compounds.
