Ytterbium(III) triflate efficiently catalyzes the one-pot reaction of homophthalic anhydride with aldehydes and amines at ambient temperature to afford the corresponding cis-isoquinolonic acid derivatives in good to excellent yields with high diastereoselectivity. This method provides a novel and much improved modification of the three-component reaction in terms of mild reaction conditions, short

Abstract ZnCl2, AlCl3-SiO2 catalyzes efficiently the three-component condensation reaction of aldehydes, amines, and homophthalic anhydride in dichloromethane to afford the corresponding cis-isoquinolonic acids in good yields at room temperature.
