Abstract
The hydrogenation of acetylacetone over asymmetrically modified Raney nickel catalyst gave the chiral diastereomer of 2,4-pentanediol selectively with high optical purity. The recrystallization of the hydrogenation product from the ethereal solution gave optically pure (2R*,4R*)-2,4-pentanediol. Thus, (−)-(2R,4R)- and (+)-(2S,4S)-2,4-pentanediol were obtained from the hydrogenation products on using (R,R)- and (S,S)-tartaric acid-NaBr-modified Raney nickel, respectively.
