Hydrogenation, catalytic oxime, stereoselective

Oximes undergo hydrogenation to hydroxylamines and/or amines depending on reaction conditions. Platinum oxide is the most frequently used catalyst for selective hydrogenation of oximes to hydroxylamines. Reduction of chiral oxime 96 over palladium catalyst (equation 66) proceeds in high yield and stereoselectivity. High stereoselectivity was observed in catalytic hydrogenation of a-alkoxyoximes . [Pg.139]

There are some reports on the asymmetric catalytic hydrogenation of C=N double bonds. Rhodium phosphine complexes do not have high activity, and the stereoselectivity is low. - Homogeneous hydrogenation of oximes, Schiff s bases and cyclic imines " have been reported. A cyano cobalt complex has been used for the homogeneous catalytic hydrogenation of oximes and Schiff s bases but the degree of asymmetric induction is unknown. [Pg.155]

The catalytic hydrogenation of optically active benzoin oxime resulted in the stereoselective formation of optically active erythro diphenylethanolconine in... [Pg.173]
