title: A stereoselective three-component reaction: KAl(SO4)2.12H2O, an efficient and reusable catalyst for the one-pot synthesis of cis-isoquinolonic acids.
abstract: KAl(SO(4))(2).12H(2)O is found to catalyze efficiently the stereoselective one-pot three-component cyclocondensation of homophthalic anhydride, aldehydes, and amines under mild conditions to afford the corresponding cis-isoquinolonic acids in good yields.
