Basolites: A type of Metal Organic Frameworks highly efficient in the one-pot synthesis of quinoxalines from alpha-hydroxy ketones under aerobic conditions
We report here efficient synthesis of quinoxalines from o-phenylendiamine and alpha-hydroxy ketones over commercial Basolites. The concentration and type of acid centres, as CUS sites, together with the porosity of the samples strongly influence the resulting conversion and selectivity. Our results indicate that the formation of quinoxalines preferentially follows a new route, in which tautomerization reactions are also involved.
