Enaminones, prepared by condensation of homoveratrylamine with 1,3-dicarbonyl compounds, undergo intramolecular cyclization in acidic media to afford 1,1-disubstituted tetrahydroisoquinolines in good yields. Further modification of the title compounds is demonstrated.

A convenient procedure for modification of β-enaminones by α-C-acylation and subsequent acidic cleavage is described. The unsymmetrical β-enamino ketones obtained in this way could be hydrolyzed to provide an entry towards various unsymmetrical 1,3-diketones.
