Studies on the Syntheses of Heterocyclic Compounds. CDLXXXVI. Behavior of the Erythrinadienone and Its Relatives in Acidic Medium

Abstract

The reductive rearrangement of the dienol (V), derrived from erythrinadienone (III), did not give the proposed dibenzazonine analog (IV), but V was converted to the dibenzazonine (VI) in methanolic hydrochloric acid solution. The catalytic hydrogenation of (III) has also been examined.
