Cationic Pd(II)-catalyzed cyclization of N-tosyl-aniline tethered alkynyl ketones initiated by hydropalladation of alkynes: a facile way to 1,2-dihydro or 1,2,3,4-tetrahydroquinoline derivatives
A cationic Pd(II)-catalyzed intramolecular alkyne-carbonyl reductive coupling reaction of N-tosyl-aniline tethered alkynyl ketones under transfer hydrogenation conditions to give hydroquinolines is developed.
