Synthesis of 2,3-Dihydroquinolin-4(1H)-ones throughCatalytic Metathesis of o-Alkynylanilines andAldehydes

摘要

SbF_5-Me0H catalytic system efficiently promotes thealkyne-carbonyl metathesis of o-alkynylaniline deriva-tives and aldehydes to afford 2,3-disubstituted dihydro-quinolinones in moderate to high yields with high trans-selectivity.
