Salicylic acid was used as an efficient catalyst for the diastereoselective synthesis of dispirohydroquinoline-bis (Meldrim's acid) derivatives via a one-pot domino eight-component reaction of arylamines, aromatic aldehydes and Meldrum's acid in CH3CN at room temperature. The remarkable advantages offered by this method are inexpensive catalyst, good yields, simple and easy work-up procedure. The characterization of products was done by IR, mass, 1H NMR, 13C NMR spectroscopy, and elemental analyses. The stereoselectivity of compounds was confirmed with crystallography and NMR spectroscopy.
