The key prenylcarbazole precursor 33 was readily assembled from diester 30 by an ester-driven para-Claisenrearrangement followed by selective removal of the ester function. Unusual oxidative cyclization of 33 by m-CPBA resulted in the total synthesis of tetracyclic carbazole natural products 3 and 11.
