  使用可可碱化学助剂通过细胞色素P450 3A4进行区域选择性环氧化，可预测产生N保护的β-或γ-氨基环氧化合物

  摘要：

  N-保护的β-和γ-氨基环氧化物是有用的手性合成子。我们在此报告，即使存在多个双键或芳族取代基，细胞色素P450 3A4酶也可以区域和立体选择性方式催化此类化合物的形成。为此，可可碱化学助剂不仅用于控制酶的选择性，而且还用作掩蔽的胺，并促进产物的回收。可可碱可预测地将可可碱基团中第四个碳的双键定向环氧化。与大多数催化剂不同，选择性不取决于电子或空间因素，而是取决于烯烃相对于可可碱的位置。

  Predictable Stereoselective and Chemoselective Hydroxylations and Epoxidations with P450 3A4

  摘要：

  Enantioselective hydroxylation of one specific methylene in the presence of many similar groups is debatably the most challenging chemical transformation. Although chemists have recently made progress toward the hydroxylation of inactivated C-H bonds, enzymes such as P450s (CYPs) remain unsurpassed in specificity and scope. The substrate promiscuity of many P450s is desirable for synthetic applications; however, the inability to predict the products of these enzymatic reactions is impeding advancement. We demonstrate here the utility of a chemical auxiliary to control the selectivity of CYP3A4 reactions. When linked to substrates, inexpensive, achiral theobromine directs the reaction to produce hydroxylation or epoxidation at the fourth carbon from the auxiliary with pro-R facial selectivity. This strategy provides a versatile yet controllable system for regio-, chemo-, and stereoselective oxidations at inactivated C-H bonds and demonstrates the utility of chemical auxiliaries to mediate the activity of highly promiscuous enzymes.

  A range of d2-labeled alkanes can be synthesized via nickel-catalyzed hydrodeuterioalkylation of deuterated alkyl thianthrenium (TT) salts with unactivated alkenes. The deuterated alkyl reagents effectively integrate deuterium from D2O via pH-dependent hydrogen isotope exchange (HIE). Our method enables high deuterium incorporation and precise control over insertion site, essential for drug synthesis
