  摘要：

  The enantioselective reduction of alkyl 3-oxobutanoates by carbonyl reductase (Sl) from Candida magnoliae was investigated. S1 reduced alkyl 4-halo-3-oxobutanoates to the corresponding enantiomerically pure (S)-3-hydroxy esters. Escherichia coli HB101 transformant co-overproducing the S1 and glucose dehydrogenase from Bacillus megaterium, produced optically pure alkyl 4-substituted-3-hydroxybutanoates in a two-phase water/organic solvent system.

  The hydrolytic kinetic resolution (HKR) of terminal epoxides catalyzed by chiral (salen)Co(III) complex 1 x OAc affords both recovered unreacted epoxide and 1,2-diol product in highly enantioenriched form. As such, the HKR provides general access to useful, highly enantioenriched chiral building blocks that are otherwise difficult to access, from inexpensive racemic materials. The reaction has several

  由手性 (salen)Co(III) 配合物 1 x OAc 催化的末端环氧化物的水解动力学拆分 (HKR) 提供了回收的未反应环氧化物和高度对映体富集形式的 1,2-二醇产物。因此，HKR 提供了从廉价的外消旋材料中获得有用的、高度对映体富集的手性结构单元的通用途径，而这些结构单元在其他方面难以获得。从实用的角度来看，该反应具有几个吸引人的特点，包括使用 H(2)O 作为反应物和低负载 (0.2-2.0 mol%) 的可回收、市售催化剂。此外，HKR 显示出非凡的范围，因为可以将各种空间和电子变化的环氧化物分解为 > 或 = 99% ee。相应的 1,2-二醇是使用 0.45 当量的 H(2)O 在良好到高对映体过量中产生的。提供了用于分离高度对映体富集的环氧化物和二醇以及催化剂回收和再循环的有用和通用的协议。HKR 反应的选择性因子 (k(rel)) 通过测量约 ee 的产物 ee 来确定。20%

  The stereochemical outcome of the intramolecular Diels-Alder reaction of ester-linked 1,3,8-nonatrienes can be controlled by substituents about a stereogenic center attached to C1. The scope and limitations of this approach have been investigated, with variation in substrate structure about the allylic stereocenter and the dienophile. The stereochemical outcomes of these reactions are explained by

  The discovery of novel tetrahydropyrrolo[1,2-c]pyrimidines derivatives from Bay41_4109 as hepatitis B virus (HBV) inhibitors is herein reported. The structure–activity relationship optimization led to one highly efficacious compound 28a (IC50 = 10 nM) with good PK profiles and the favorite L/P ratio. The hydrodynamic injection model in mice clearly demonstrated the efficacy of 28a against HBV replication
