  名称：

  Candida antarctica lipase A and Pseudomonas stutzeri lipase as a pair of stereocomplementary enzymes for the resolution of 1,2-diarylethanols and 1,2-diarylethanamines

  摘要：

  Candida antarctica lipase A (CALA) and Pseudomonas stutzeri lipase (PSL) displayed opposite enantioselectivities in the acylation of 1,2-diphenylethanol and 1,2-diphenylethanamine. CALA was (S)-selective while PSL was (R)-selective. In addition, fourteen different 1,2-diarylethanols were tested as the substrates of CALA. It was found that most of them were accepted by CALA with high enantioselectivity. The DKR of five representative substrates by the combination of CALA and a ruthenium-based racemization catalyst provided good yields (82-91%) and acceptable enantiopurities (87-94% ee).

  摘要：

  使用单一 Pd 催化剂，通过 MPV 型氢转移过程实现的借氢催化，开发了仲醇与芳基溴的 β-芳基化的第一个例子。此外，在Pd和Ru的催化下也实现了该反应的对映异构体，使得外消旋仲醇转化为具有良好对映选择性的对映异构体丰富的手性醇。

  catalyst, the first example of β-arylation of secondary alcohols with aryl bromides has been developed via borrowing hydrogen catalysis enabled by an MPV type hydrogen transfer process. In addition, the enantioconvergent version of the reaction has also been realized under the catalysis of Pd and Ru, allowing for the transformation of racemic secondary alcohols into enantioenriched chiral alcohols with good
