Asymmetric hydrogenation of 2-arylcycloalkanones with trans-RuCl2(binap)(1,2-diamine) and t-C4H9OK in 2-propanol selectively gives the corresponding cis-2-arylcycloalkanols in excellent enantiomeric purity and high yield. Two synthetic intermediates of biologically active compounds have been prepared by this method.
用反式-RuCl2(binap)(1,2-二胺)和 t-C4H9OK 在 2-
丙醇中对 2-芳基环烷酮进行不对称氢化,可选择性地得到相应的顺式-2-芳基环烷醇,对映体纯度极高,产率也很高。用这种方法制备了两种
生物活性化合物的合成中间体。
