Abstract

The mode of enantioface-differentiating hydrogenation with asymmetrically modified Raney nickel (MRNi) was investigated by using various sorts of modifying reagents and substrates. The optical yields (OY) of the hydrogenation of methyl acetoacetate over MRNi for different modifying reagents occured in the following order:(Remark: Graphics omitted.),(Remark: Graphics omitted.). The hydrogenation of various substrates of the structure,(Remark: ...
