Recent Advances in the Synthesis of Azonia Aromatic Heterocycles

Azonia aromatic heterocycles are an important subclass of azaheterocyles as they are the structural motif of relevant cationic alkaloids, and they have a wide range of potential applications such as bioactive compounds and organic materials. In this Synopsis, recent and novel approaches to their synthesis are surveyed, with particular emphasis on ring-closing metathesis reactions and annulation reactions based on C-H activation.
