Logical design and synthesis of indole-2,3-diones and 2-hydroxy-3(2H)-benzofuranones via one-pot intramolecular cyclization

Add time:08/15/2019    Source:sciencedirect.com

A novel and attractive protocol to synthesis indole-2,3-diones and 2-hydroxy-3(2H)-benzofuranones and via copper(II) oxide catalyzed intramolecular cyclization is described. This method possesses functional-group compatibility, easy workup procedure, shorter reaction time and high yields.
