Chiral ureas and thioureas supported on polystyrene for enantioselective aza-Henry reactions under solvent-free conditions

Novel bifunctional ureas and thioureas immobilized on sulfonylpolystyrene have been prepared as recoverable and reusable organocatalysts and have been used in the stereoselective aza-Henry reaction under solvent-free conditions. The activity and stereoselection of the catalysts are dependent on the length of the tether bridging the active site and the polymer, the catalyst derived from 1,6-hexane diamine being the best one. It has also been demonstrated that the supported catalysts are more effective than the homologous soluble catalysts.

Diastereoselective addition of enantiopure lithium tert- butylsulfinylferrocene to imines

(S)-terf-Butylsulfinylferrocene was submitted to ortho-metalation, and the corresponding lithium derivative was trapped by alkyl or aryl imines bearing various electron-withdrawing groups on the nitrogen atom (Ts, Dpp, Boc). New aminosulfoxides were obtai
