developed. This method features conversion of pyridotriazoles into two N-fused heterocyclic aromatic systems—imino-thiazolopyridines and oxo-thiazolopyridine derivatives—via one-step Co(II)-catalyzed transannulation reaction proceeding via a radical mechanism. The synthetic usefulness of the developed method was illustrated in the synthesis of amino acid derivatives and further transformations of obtained
