一般說明

Cyanoborohydride, polymer supported: is a polymer-supported reducing agent used in reductive amination reactions at room temperature.

應用

Polymer supported cyanoborohydride (PSCBH) has been used in the reductive alkylation aminocyclitols for the preparation of corresponding secondary amines.
It can also be used:
  • In combination with manganese dioxide (MnO2) for one-pot conversion of alcohols to secondary or tertiary amines.
  • In the synthesis of natural products, (±)-oxomaritidine and (±)-epimaritidine.
