VIII族遷移金属解媒による高立体選択的水素化反応

抄録

A number of stereoselective hydrogenations have been known that are catalyzed by Group VIII transition metals or their complexes. In most cases, however, a mixture of stereoisomers results and it is rather a few cases that lead to only one stereoisomer quantitatively or in very high selectivity. In the following are described some recent examples that are highly stereoselective and would be useful for organic syntheses or of interest from the viewpoint of hydrogenation mechanisms. The article covers 1) the hydrogenation of acetylenic bonds; 2) the hydrogenation of olefinic bonds; 3) the hydrogenation of α, β-unsaturated ketones; 4) the hydrogenation of alicyclic ketones; 5) asymmetric hydrogenations.
