The first organocatalyticasymmetric reaction employing 3,4-dihydro-2-quinolone has been developed leading to the synthesis of biologically important 3,3-disubstituted-dihydro-2-quinolones. Cinchona alkaloid derived bifunctional amino-thiourea catalysts were found to be the best catalysts. The products were obtained in high enantio- and good diastereoselectivities and also few synthetic transformations

An organocatalytic enantioselective Mannichreaction between dihydro‐3‐carboalkoxy‐2‐quinolones and preformed N‐Boc imines has been developed. Quinine derived thiourea catalyst was found to be effective to provide the desired products in good yields and with good enantioselectivities.
