Abstract

In this work, we continue our adventure in the chemistry of 5-5 tri-nitrogen bicycles. We disclose herein a one-step reaction to synthesize 1H-imidazo[1,5-a]imidazoles with different substituents introduced through the use of a wide range of aldehydes and isocyanides by using a Groebke–Blackburn–Bienaymé multicomponent reaction. The aim is to build a new library of 1H-imidazo[1,5-a]imidazole scaffolds. This bicycle was then modified to access new nitrogen-containing polycyclic compounds.
