Photocarboxylation of Arylated 2H‐Azirines Exploiting Continuous Flow Technology

European Journal of Organic Chemistry, EarlyView.
An efficient continuous process for the synthesis of trisubstituted oxazoles is reported which links the photochemical opening of azirines and the subsequent trapping of the azomethine ylides with CO2 gas. This highlights challenges and solutions when incorporating CO2 as a feedstock material for the photochemical synthesis of small heterocyclic ...

Computational Design, Synthesis, and Biological Assessment of Some Pyrrolo[3,4‐c]Pyrroles Targeting Mycobacterium Tuberculosis

ChemistrySelect, Volume 10, Issue 17, May 5, 2025.
A new set of spirooxindole‐ and spiroindenoquinoxaline‐derived pyrrolo[3,4‐c] pyrroles has been synthesized through atom‐economic one‐pot multicomponent reactions. Based on the results, compounds 4b and 5a demonstrated promising Glide scores and exhibited strong binding affinity with decaprenylphosphoryl‐β‐D‐ribofuranose oxidoreductase.
