Base-initiated oxidation of alkylindeneanilines by oxygen
Oxidation and alkylation processes compete in the oxidative transformation of alkylindeneanilines in an alkaline medium.Oxidation leads mainly to the formation of formanilide anbd the corresponding carbonyl compound.Alkylation leads to a product which easily eliminates the aniline molecule with the formation of a derivative of the 1-aza-1,3-diene.A combination of alkylation and oxidation led to derivatives of quinoline.It is assumed that the alkylation-dehydrocyclization-elimination of alkylindeneanilines to quinolines by the action of oxygen and alkali is a variant of the Doebner-Miller reaction.During oxidation in the presence of sodium borohydride the products from conjugate oxidation-reductiono, i.e., the α-imino and β-amino alcohols, are also formed in addition to quinolines and oxidation and alkylation products.
