Application of organocatalysts

Our research can be divided into 6 main parts:

  1. Synthesis of cyclodextrin-cinchona organocatalysts containing thiourea or squaramide unit, and their application in asymmetric syntheses; catalyst recovery by OSN technique

  2. Synthesis of piperidine-camphor sulfonamide derivatives, and their application in Michael additions

  3. Michael addition reactions of N-Heterocycles

  4. Optimization of aza-Markovnikov additions catalyzed by different cinchona derivatives

  5. Synthesis of new axially chiral organocatalysts containing bis-1,1'-binaphthyl unit; attaching some of them to PBI membrane by click reaction

  6. Immobilization of cinchona squaramide to polyglycidyl methacrylate support and its application in asymmetric synthesis
