Abstract:
Treatment of 4-acyl-1,2-dihydroisoquinolines with the Meerwein reagent (triethyloxonium tetrafluoroborate) produces vinylogues of the ethoxyimminium cations in high yield. With a view to developing syntheses of 3-substituted isoquinoline derivatives, some reactions of these salts with nucleophilic reagents have been examined.
