Oxidant-free annulation of α-hydroxy ketones with diamines using aluminum(III) chloride: A supramolecular approach for practical quinoxaline synthesis

Results in Chemistry
The conventional reaction of α-hydroxy ketones (acyloins) with arene-1,2-diamines typically requires an oxidant to facilitate a tandem oxidative condensation, resulting in quinoxaline derivatives. In this study, an innovative approach has been introduced
