  Evaluation of an esterase annotated as 26D isolated from a marine metagenomic library is described. Esterase 26D was found to have a unique substrate scope, including synthetic transformations which could not be readily effected in a synthetically useful manner using commercially available enzymes. Esterase 26D was more selective towards substrates which had larger, more sterically demanding substituents

  描述了评估从海洋宏基因组库中分离为26D的酯酶的方法。发现酯酶26D具有独特的底物范围，包括使用市售酶不易以合成有用的方式实现的合成转化。酯酶26D是更具选择性的朝向具有较大的，更空间要求的取代基的底物（即，异-丙基或叔-丁基基团）上的β碳，这是相对于其中显示的偏好基板与空间位先前测试的市售的酶β-碳原子上的取代基（例如甲基）要求较低。

  using a chiral diene(L*)‐rhodium catalyst. Through this methodology, we are able to obtain various secondary amides, containing a tertiary α‐stereocenter and a β,γ‐unsaturated gem‐difluoro olefin, with excellent enantioselectivities. This methodology addresses the limitations of the previously described α‐arylation methods to construct stereo‐labile tertiary α‐stereocenters. Further investigation of the

  我们利用电子偏置迈克尔受体的反应性，使用手性二烯（L *）-铑催化剂进行脱氟α-芳基化反应。通过这种方法，我们能够获得各种仲酰胺，其中包括叔α-立体中心和β，γ-不饱和宝石-二氟烯烃，具有出色的对映选择性。该方法论解决了先前描述的α-芳基化方法构建立体不稳定的三级α-立体中心的局限性。通过原位19 F NMR监测反应的进一步研究表明，产物的形成导致活性铑催化剂的抑制。

  Treatment of β-fluoroalkylated-α,β-unsaturated ketones with 1.2 equiv. of various arylboronic acids in the presence of 5 mol% of [Rh(COD)2]BF4 and 6 mol% of (S)-BINAP in toluene/H2O (v/v = 4/1) at the reflux temperature for 3 h gave the corresponding Michael adducts in high yields with over 90% enantioselectivity. Though other electron-deficient alkenes, such as vinylsulfone and vinylphosphonate, were found to be much less reactive in the rhodium-catalyzed conjugate addition with arylboronic acids, the reaction of various arylstannanes toward such electron-deficient alkenes took place very smoothly to afford the corresponding adducts in high yields.

  在甲苯/H2O（v/v = 4/1）溶液中，加入 5 摩尔的[Rh(COD)2]BF4 和 6 摩尔的(S)-BINAP，在回流温度下，用 1.2 等份的各种芳基硼酸处理δ-氟烷基化-δ,δ-不饱和酮 3 小时，可得到相应的迈克尔加合物，产率高，对映选择性超过 90%。虽然其他缺电子烯类，如乙烯基砜和乙烯基膦酸，在铑催化的芳基硼酸共轭加成反应中反应性要差得多，但各种芳基锡烷与这些缺电子烯类的反应非常顺利，能以高产率得到相应的加合物。
