摘要
Chiral diamines having a C-2 symmetry, (4S,5S)-2,2-dimethyl-4,5-bis(aminomethyl)-1,3-dioxolane and (5S,5'S)-2,2,2',2'-tetramethyl-3,3'-diphenyl-5,5'-bioxazolidine, were synthesized on the basis of (+)-(2R,3R)-tartaric acid. Their structure was proved by X-ray analysis. The products were used as ligands in rhodium catalyst for enantioselective hydrogenation of alpha-acetamidocinnamic and itaconic acids.
