โฆ Synopsis
Hydroxyketones and diketones have been reduced with lithium indium hydride to give meso-diols selectively, cยข-Hydroxyketones and 0c-diketones are reduced to meso-l,2-diols with high diastereoselectivities, whereas the selectivities of ~hydroxyketones and [~diketones are less satisfactory.

The reductive amination of 25hexanedione and 2,6-heptanedione with ammonia and primary amines in the presence of hydride reagents afforded 2,!5dimethylpyrrolidines and 2.6-dimethylpipexidines with variable diastereoselectivity, as the cislrrans ratio was affected by the size of the ring formed and t
