The inability to replace these AlO x complex ions by alkali metal ion exchange indicates their complex structure. These extraframework AlO x species localized inside the zeolite void volume of beta zeolites represent highly active sites in the stereoselective MPV reduction of ketone to cis-alcohol, ...

PURPOSE:To inexpensively and simply produce and separate an optically active alcohol having different absolute configuration by subjecting a prochiral ketone compound to asymmetric reduction using a specific optically active ligand in an extremely small amount. CONSTITUTION:A ketone compound, particularly ar...
The class I (alpha, beta 1, gamma 1, and gamma 2), II (pi), and III (chi) isozymes of human liver alcohol dehydrogenase (ADH) were isolated as electrophoretically homogeneous preparations to examine their kinetics of aldehyde and ketone reduction. While the oxidation of a wide variety of...
