Many components make light work: A novel synthetic strategy for the preparation of pyridines and isoquinolines in high chemo‐ and regioselectivity has been developed. By manipulating the reaction conditions, either product can be generated smoothly in a highly efficient and atom‐economic manner (see scheme).

strategy for polysubstitutedpyridines and isoquinolines with high chemo- and regioselectivity. In this methodology, 1-alkynyl imines act as the key compound to undergo a sequential alkynyl imine–allenyl imine isomerization/aza-Diels–Alder reaction/aromatization. In the first place, 1-alkynyl imines were formed in situ by a highly selective multicomponentreaction of isocyanides, arynes, and terminal alkynes
