The 2-alkenylthiopyranoquinoline-3-carbaldehyde derived from 2-mercaptoquinoline-3-carbaldehyde and citral underwent smooth domino Knoevenagel/hetero-Diels-Alder reaction with heterocyclic mono- or diketones in tetrabutylammonium hydrogensulfate under solvent-free conditions and afforded a new class of thiochromenoquinoline-fused heterocycles in good yields. The reaction is highly diastereoselective and can be applied to analogs of carbocyclic diketones as well. The stereochem. of the products was confirmed by single-crystal X-ray diffraction and 2D NMR NOESY data.
