Abstract
A simple, facile, and highly efficient approach has been unfolded for the syntheses of ?-carboline tethered imidazole derivatives. This expeditious catalyst-free strategy proceeds through the assembly of 1-formyl-9H-?-carbolines, glyoxal derivatives and ammonium acetate via the formation of concomitant four C?N bonds in a one-pot operation. The current approach has various advantages, including multicomponent nature, simple reaction conditions, short reaction time, broad substrate scope, and high product yield. Importantly, the ?-carboline tethered imidazole derivatives displayed excellent photophysical properties with quantum yield up to 90%. � 2023 Wiley-VCH GmbH.
