Synthesis of 1,2-aminoazides. Conversion to unsymmetrical vicinal diamines by catalytic hydrogenation or reductive alkylation with dichloroboranes.
摘要:
1,2-aminoazides are easily prepared from 1,2-amino alcohols. Catalytic hydrogenation in the presence of palladium on charcoal or reductive alkylation with dichloroboranes afford with good yields unsymmetrically substituted vicinal diamines.
