Popis: 1,3,3-Trimethyl-3,4-dihydroisoquinolines, which exist in the imine form, undergo C- hydroxyalkylation upon reaction with hexafluoroacetone and esters of trifluoropyruvic acid at the C1 CH3 group at 20°C. The products with the ketoesters are converted upon heating to γ-lactams. Derivatives of 1,3,3-trimethyl-3,4-dihydroisoquinoline substituted at C1 CH3 group and existing in the enamine form, react with esters of trifluoropyruvic acid at 20°C to give exclusively γ-lactams and do not give reaction products with hexafluoroacetone.
