A range of sulfides can be selectively oxidized to the corresponding sulfoxides in good yields using catalytic quantities of heterocyclic amine salts (quinoline, cinchonine, and cinchonidine) of Keggin heteropolyacids with different green oxidants. The cinchonine heteropolyacid catalyst is easily recoverable and reusable without loss of its catalytic activity, and an enantiomeric excess can be obtained.

3,4-Dihydropyrimidin-2(1 H)-ones were synthesized in good yields by solvent-free one-pot three-component Biginelli condensation in the presence of molten tetrabutylammonium bromide or ammonium bromide as catalyst,irrespective of the presence of electron donating or electron withdrawing groups aromatic aldehydes.
