Chemistry of indoles carrying a basic function. Part IX. Unexpected cyclizations of diketones derived from Uhle's ketone

Starting from a tricyclic diketone (14) obtained by Bowman's method, a tetracyclic oxonaphthalene derivative (17) has been prepared through intramolecular aldol condensation followed by indole → naphthalene isomerization. An unexpected formation of a lact
