A Sydnone-Based Route to Indazolo[2,3-a]quinoxaline Derivatives

Abstract A new synthetic route to indazolo[2,3- a ]quinoxaline derivatives is described. The strategy is based on the 1,3-dipolar cycloaddition of arynes to quinoxaline–sydnone derivatives as a key step. The polyaromatic sydnones were prepared through a copper-promoted intramolecular cyclization of...

Description
Summary:Abstract A new synthetic route to indazolo[2,3- a ]quinoxaline derivatives is described. The strategy is based on the 1,3-dipolar cycloaddition of arynes to quinoxaline–sydnone derivatives as a key step. The polyaromatic sydnones were prepared through a copper-promoted intramolecular cyclization of the C-4 position of sydnones on imines.
