  Polystyrene-immobilized pyrrolidine as a highly stereoselective and recyclable organocatalyst for asymmetric Michael addition of cyclohexanone to nitroolefins

• Mark:

  Table 4

• Associated context:

  After carrying out the reaction, the reaction solution was vacuum filtered using a sintered glass funnel and washed with CH₂Cl₂ (CAS 75-09-2) (2 mL), Et₂O (CAS 60-29-7) (2 mL), C₂H₅OH (CAS 64-17-5) (2 mL), and hexane (2 mL), respectively. It can be reused directly without further purification. The 4 could be recovered, recycled, and used for 10 consecutive trials without loss of activity (Table 4).
