The asymmetric reduction of ketoxime ethers to yield enantiomerically enriched chiral hydroxylamines with reagents prepared from borane and norephedrine has been investigated. Very high enantioselectivity (ca. 99% ee) was obtained in the reduction of ketoxime O-(o-nitrobenzyl) ether to O-(o-nitroben
