Efficient catalytic hydrogenation of N-unsubstituted cyclic imides to cyclic amines

The hydrogenation of N-unsubstituted cyclic imides to the corresponding cyclic amines has been performed selectively with heterogeneous catalysts obtained from rhodium and molybdenum carbonyl precursors. Various substrates were reduced in good to high yields and selectivities. Platinum-based catalysts also proved to be efficient. Furthermore, gram-scale experiments were performed and the catalysts could be recycled.

Study of a reduction step during the continuous synthesis of N-amino-3-azabicyclo[3.3.0]octane. Kinetics, modelling, and optimization

The reduction of N-chloro-3-azabicyclo[3.3.0]octane with sodium borohydride at different pH values and variable concentrations of the haloamine and reducing agent was studied. The reaction was found to be second order and exhibited a specific acid catalysis. The enthalpy and entropy of activation were determined at pH 12.89. A mathematical treatment of the kinetic data allowed a complete characterization of the final state and the determination of percentage of haloamine reduced as a function of temperature, [NaBH4]/ [haloamine] ratio, arid pH. A reaction mechanism is proposed.
