In situ oxidation-imine formation-reduction routes from alcohols to amines

[GRAPHICS] Manganese dioxide is employed as an in situ oxidant for the one pot conversion of alcohols into imines, In combination with polymer-supported cyanoborohydride (PSCBH), a one-pot oxidation-imine formation-reduction sequence is reported, This procedure enables alcohols to be converted directly into both secondary and tertiary amines.
