In recent years,iron salts,being effective,alternative,and promising transition-metal catalysts,have received much more attention because of their low cost,abundance,and environmentally benign properties.In particular,FeCl3 has been widely applied as a Lewis acid catalyst for the catalytic synthesis of heterocyclic compounds,multicomponent reactions,cross-coupling reactions,and cyclization reactions.Previously,we developed an efficient synthetic approach to coumarins and polysubstituted pyridines using FeCl3-catalyzed one-pot cascade and multicomponent reactions.1-3Herein,we have developed a series of synthetic approaches for the construction β-alkynyl ketones,4 and 9-substituted-2,3,4,9-tetrahydro-1H-xanthen-1-ones5 via FeCl3-catalyzed domino reactions of propargylic amines/diaryl amines and 1,3-diketones.
