An iodine-promoted one-pot cascade oxidative annulation reaction has been developed for the synthesis of [1,2,3]triazolo[1,5-a]quinolines from methyl azaarenes and N-tosylhydrazines. The reaction has a broad substrate scope and can be easily scaled up to gram-scale. 1,2,3-Triazoles are an important skeletal structure for the construction of C?C and C?P bonds, 2-cyclopropylquinolines and imidazo[1,5-a]quinolines, for which different synthetic applications were explored.

A new inexpensive copper-catalyzed denitrogenative C?P coupling reaction of pyridotriazoles with P(O)H compounds has been developed. The reaction proceeds via a process of copper-catalyzed P(O)?H insertion into the pyridyl carbene intermediates generated in situ from pyridotriazoles. This reaction provides a new and effective method for the synthesis of a variety of 2-picolylphosphoryl compounds. (Figure presented.).
