    • The spectroscopic data obtained for all new compounds were fully consistent with the assigned structures. Reaction conditions have not been optimized. All yields are isolated yields.

    • We believe that capricious water causes the Lewis acid to hydrolyze the enol ether to form enedione 19a. Intramolecular addition of the arene to ketone 19a, followed by rearomatization of the C ring, produces 19b. Dehydration of the tertiary alcohol results in the aromatization of the B-ring. {A figure is presented}

    • In related work, we have found that the C(l),C(10)-double bond of diene 12 readily isomerizes into conjugation with the C(6),C (7)-double bond upon exposure to either protic or Lewis acids. Thus in the first step, the oxidant adds to the C(I) carbon with migration of the double bond into the ring fusion (cf. 12ii).This intermediate is then further oxidized to generate conjugated dienone. {A figure is presented}
