A NaOH-mediated sustainable synthesis of functionalized quinoxalines is disclosed via redox condensation of onitroamines with diols and α-hydroxy ketones. Under optimized conditions, various o-nitroamines and alcohols are well tolerated to generate the desired products in 44−99% yields without transition metals and external redox additives.

A Ru or Rh-catalyzed direct C7 allylation of indolines with vinylcyclopropanes via sequential C–H/C–C activation under microwave irradiation has been disclosed.
