摘要
Formula (i) (in formula, R1, is alkyl, aryl, or the hetero aryl basis which are substituted by H or case, R2, is alkyl, aryl or the hetero aryl basis which are substituted by when, as for R3, being the method of hydrogenating asymmetrically H or C1 - C6 alkyl groups is) the acrylic acid derivative, making use of the transition metal catalyst, the chemical compound formula (i), in the solvent with when, in 1 kinds or under existing of the hydrogen donor above that, the transition metal from the group of ruthenium, rhodium, and iridiumFormula (ii) (in formula, Cn, 2 oxygen atoms and the phosphorus atom and becoming simultaneous, forms the ring which is substituted by when it possesses 2 - 6 carbon atoms, R4, alkyl, aryl, the alkoxy, or aryl oxy basis or NR5R6 which are substituted by when (in formula, becoming independent respectively, may be alkyl, aryl, the aralkyl, or the arukariru basis which are substituted by H or case, or the nitrogen atom and becoming simultaneous, ring R5 and R6, is possible) is) kiraru to form the phosphorus ligand and formula(iii) (in formula, as for R, formula (iv) it corresponds is substituted the alkyl or aryl basis which is by when) akiraru making use of the catalyst system which includes with the combination of the phosphine ligand, (in formula, as for R1, R2, and R3, the respective description above and synonymy is) in addition to the method of including the fact that it hydrogenates in chemical compound, new catalyst system for the asymmetrical transition metal catalyst reaction. Selective figure It is not
