[reaction: see text] A facile preparation of chiral alpha-aryloxy carboxylic acids via asymmetric hydrogenation of the corresponding unsaturated acids has been discovered. A number of catalysts have been identified that give high product enantioselectivity, and the scope of the reaction has been examined with respect to substitution on the aromatic ring and olefin.
[反应:见正文]已经发现通过相应的不饱和酸的不对称加氢来制备手性α-芳氧基羧酸的简便方法。已经鉴定出许多提供高产物对映选择性的催化剂,并且已经就芳香环和烯烃上的取代检查了反应范围。
