- ... A method of furo-annulation of 4-hydroxy-2-oxoquinoline-3-carboxylates with 3-arylazirines under Cu(II) catalysis was developed to synthesize a variety of 2,3-dihydrofuro[3,2-c]quinolones bearing a carbamate group at the C2 position. The reaction involves an azirine ring opening across the N–C2 bond and formation of a dihydrofuran ring with the inclusion of two azirine carbon atoms, accompanied by ...
