A mild and efficient synthesis of spiroquinolinones 6 via condensation of chlorooxoindolines 5 and benzene-1,2-diamines 3 is reported. Instead of expected spirooxindole product 4′, spiroquinolinones 6 were isolated in up to 95% yield. A plausible mechanism involving an interesting ring rearrangement to form spiroquinolinones is proposed.
