  在水性介质中从顺序反应到并发反应：钌催化的烯丙醇异构化和不对称生物还原

  摘要：

  在水性介质中同时进行的钌催化的烯丙醇氧化还原异构化与对映选择性酶酮还原（由KRED介导）成功地结合在一起。在温和的反应条件下，采用可商购和容易获得的催化体系，并且没有外部辅酶或辅因子，总转化，即烯丙基醇的不对称还原，以优异的转化率和对映选择性进行。优化导致了多步骤方法和真正的级联反应，其中金属催化剂和生物催化剂从一开始就共存。

  Efficient and modular syntheses of chiral 2-(2-hydroxyaryl)alcohols (HAROLs), novel 1,4-diols carrying one phenolic and one alcohol hydroxyl group, have been developed which led to generation of a small library of structurally diverse HAROLs in enantiomerically pure form. Of the different HAROLs examined, a HAROL based on the indan backbone exhibited the highest activity and enantioselectivity in the

  Novel spiroborate esters derived from non-recemic 1,2-amino alcohols were examined as chiral catalyst in the borane reduction of acetophenone and other aromatic ketones at room temperature. The optically active alcohols were obtained in excellent chemical yields and up to 99% ee with less than 10% catalyst.

  The chiral M-CsDPEN [M = Ru, Rh, Ir; CsDPEN = (R,R,R)- or (S,S,S)-N-camphorsulfonyl-1,2-diphenylethylenediamine] catalysts have been shown to be efficient for the asymmetric transfer hydrogenation (ATH) of aryl ketones by formate in neat water. Of particular note is the Ir-(R,R,R)-CsDPEN catalyst, which catalyzes the ATH of a wide range of ketones and delivers almost full conversions within a few hours at a S/C ratio of 1000 at 40 °C in most cases, with enantioselectivities up to 98% ee.

  Twenty chiral 1,3-amino sulfonamides of two classes (2a–i and 3a–k) have been prepared from (−)-cis-2-benzamidocyclohexanecarboxylic acid (1) and studied as ligands for catalytic enantioselective addition of Et2Zn to a variety of aromatic and aliphatic aldehydes. The ligands 2 and 3 are regioisomers in which the position of the amine and sulfonamide groups is exchanged. Each class of ligands with the
