Asymmetric syntheses. Part IV. The stereochemistry of the reduction of cyclohexanones

Abstract
Reduction of 3,3,5-trimethylcyclohexanone with cyclic complexes of lithium aluminium hydride are described. The axial–equatorial ratio of the cyclohexanols obtained from these and other reductions are interpreted by postulating participation of the flexible form of the ketone in the reaction.
