  摘要：

  我们实现了从阿维链霉菌NBRC14893全细胞中纯化三种α-酮基酯还原酶（阿维链霉菌酮酯还原酶，SAKERs-I，-II和-III）。通过凝胶过滤色谱法，天然SAKERs-I，-II和-III的分子量分别估计为72、38和36kDa。通过SDS-聚丙烯酰胺凝胶电泳，SAKERs-I，-II和-III的亚基分子量也分别估计为32、32和34 kDa。纯化的SAKERs-II和-III对α-酮酸酯（特别是丙酮酸乙酯）具有还原活性。SAKER-1不仅对α-和β-酮酯具有高还原活性，而且对α-酮酸也具有高还原活性。SAKERs-I，-II，的N端氨基酸序列

• Cationic Ir/Me-BIPAM-Catalyzed Asymmetric Intramolecular Direct Hydroarylation of α-Ketoamides
  作者：Tomohiko Shirai、Hajime Ito、Yasunori Yamamoto

  DOI：10.1002/anie.201400147

  日期：2014.3.3

  Asymmetric intramolecular direct hydroarylation of α‐ketoamides gives various types of optically active 3‐substituted 3‐hydroxy‐2‐oxindoles in high yields with complete regioselectivity and high enantioselectivities (84–98 % ee). This is realized by the use of the cationic iridium complex [Ir(cod)2](BArF4) and the chiral O‐linked bidentate phosphoramidite (R,R)‐Me‐BIPAM.
