P. Gamez et al., ASYMMETRIC CATALYTIC REDUCTION OF PROCHIRAL KETONES WITH SUPPORTED METAL-COMPLEXES, Bulletin de la Societe chimique de France, 131(5), 1994, pp. 600-602
Several prochiral ketones have been reduced by hydride-transfer reduct
ion catalyzed by a non-covalently bonded supported catalyst. The react
ion gave up to 99% enantiomeric excess at 100% conversion in the case
of methyl phenyl-pyruvate. Furthermore, with other substrates an incre
ase in the enantiomeric excess was obtained without a decrease in conv
ersion. This was achieved by using a continuous flow reactor.
