Intramolecular Oxidative Cyclization

A convenient and practical method has been developed for the synthesis of substituted oxazolo[5,4-h]pyrrolo[4,3,2-de]quinolones via the intramolecular oxidative cyclization by using PIFA as oxidant and TMSOTf as additive in DCE under an air atmosphere. The reaction proceeds in good yields and has good functional groups tolerance.
