Abstract
Despite its challenges, the skeletal editing of mono-azaarenes (pyridines, quinolines,
and isoquinolines) has shown unparalleled synthetic utility in the construction of complex molecules that are difficult to
access by conventional methods. In this short review, we summarize the three most
recently developed skeletal editing strategies for the deconstruction of azaarene
cores, with a focus on their generality, limitations, and mechanistic aspects. Also,
the application of the skeletal editing strategy in the total synthesis of some important
natural products is discussed.
