Visible light-promoted synthesis of 4,6a-dihydropyrrolo[3,4-c]pyrrole-1,3(2H,3aH)-dionesvia[3+2] cycloaddition reaction of 2H-azirines with maleimides

Abstract

A visible light-induced diastereoselective synthesis of 4,6a-dihydropyrrolo[3,4-c]pyrrole-1,3(2H,3aH)-diones using 2H-azirines and maleimides in the presence of an organic photocatalyst is reported. The method is efficient and environmentally friendly, and proceeds with...
