Tandem Vicarious Nucleophilic Substitution of Hydrogen/Intramolecular Diels- Alder Reaction of 1,2,4-Triazines into Functionalized Cycloalkenopyridines.
8-tetrahydroquinolines and 5,6,7,8-tetrahydroisoquinolines from 1,2,4-triazine derivatives is reported. Introduction of an alpha-functionalized methyl substituent (e.g. arylsulphonyl, sulphonamide, sulphonic acid ester) into position 3- or 6- of triazines by vicarious nucleophilic substitution of hydrogen and subsequent alkylation with alkyl iodides bearing an acetylenic function in terminal position afforded valuable
