KAl(SO4)2·12H2O is found to catalyze efficiently the stereoselective one-potthree-component cyclocondensation of homophthalic anhydride, aldehydes, and amines under mild conditions to afford the corresponding cis-isoquinolonic acids in good yields.

A mild and stereoselective three-component one-step synthesis of cis-isoquinolonic acid using silica sulfuric acid as a heterogeneous catalyst from an aldehyde, amine and homophthalic anhydride in acetonitrile is described. This new method produces pure products in high yields (81-91%).
