Abstract
Condensation of dimedone with 1,1,2-tribenzoylethylene provided pentaketone, where the position of the keto-enol equilibrium in the dibenzoylmethane fragment depended on external factors. In reactions with N-nucleophiles the pentaketone behaves as 1,4-diketone, affording with ammonium acetate, methylamine, and hydroxylamine hydrochloride functional derivatives of 4,5,6,7-tetrahydroindole, and with hydrazine hydrate, a pyridazine derivative.
