1,1-Disubstituted tetrahydroisoquinolines from enaminones via Pictet-Spengler reaction
Venkov, Atanas P.,Angelov, Plamen A.
, p. 3025 - 3033 (2003)
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
