  Targeting the gatekeeper residue in phosphoinositide 3-kinases

  摘要：

  A single residue in the ATP binding pocket of protein kinases-termed the gatekeeper-has been shown to control sensitivity to a wide range of small molecule inhibitors (Chem. Biol. 2004, 11, 691; Chem. Biol. 1999, 6, 671). Kinases that possess a small side chain at this position (Thr, Ala, or Gly) are readily targeted by structurally diverse classes of inhibitors, whereas kinases that possess a larger residue at this position are broadly resistant. Recently, lipid kinases of the phosphoinositide 3-kinase (PI3-K) family have become the focus of intense research interest as potential drug targets (Chem. Biol. 2003, 10, 207; Curr. Opin. Pharmacol. 2003, 3, 426). In this study, we identify the residue that corresponds structurally to the gatekeeper in PI3-Ks, and explore its importance in controlling enzyme activity and small molecule sensitivity. Isoleucine 848 of p110 alpha was mutated to alanine and glycine, but the mutated kinase was found to have severely impaired enzymatic activity. A structural bioinformatic comparison of this kinase with its yeast orthologs identified second site mutations that rescued the enzymatic activity of the 1848A kinase. To probe the dimensions of the gatekeeper pocket, a focused panel of analogs of the PI3-K inhibitor LY294002 was synthesized and its activity against gatekeeper mutated and wild-type p110 alpha was assessed.

  Iridium-Catalyzed Borylation of Secondary Benzylic C–H Bonds Directed by a Hydrosilane

  摘要：

  Most functionalizations of C-H bonds by main-group reagents occur at aryl or methyl groups. We describe a highly regioselective borylation of secondary benzylic C-H bonds catalyzed by an iridium precursor and 3,4,7,8-tetramethyl-1,10-phenanthroline as the ligand. The reaction is directed to the benzylic position by a hydrosilyl substituent. This hydrosilyl directing group is readily deprotected or transformed to other functional groups after the borylation reaction, providing access to a diverse set of secondary benzylboronate esters by C-H borylation chemistry.

• Iridium-Catalyzed Arene <i>Ortho</i>-Silylation by Formal Hydroxyl-Directed C−H Activation
  作者：Eric M. Simmons、John F. Hartwig

  DOI：10.1021/ja1086547

  日期：2010.12.8

  the ortho-silylation of aryl ketone, benzaldehyde, and benzyl alcohol derivatives has been developed in which a hydroxyl group formally serves as the directing element for Ir-catalyzed arene C-H bond activation. One-pot generation of a (hydrido)silyl ether from the carbonyl compound or alcohol is followed by dehydrogenative cyclization at 80-100 °C in the presence of norbornene as a hydrogen acceptor

  report herein a dynamic kinetic resolution (DKR) involving ortho‐quinone methide (o‐QM) intermediates. In the presence of Et3N and the cinchonine‐derived nucleophilic catalyst D, the DKR of 2‐sulfonylalkyl phenols with allenic esters afforded chiral benzylic sulfones in 57–79 % yield with good to excellent enantioselectivity (85–95 % ee). Furthermore, with 2‐(tosylmethyl)sesamols or 2‐(tosylmethyl)naphthols

  我们在这里报告了动态动力学拆分（DKR），涉及邻二甲基苯醌（o- QM）中间体。在Et 3 N和辛可宁衍生的亲核催化剂D的存在下，2-磺酰基烷基苯酚与烯丙酸酯的DKR可以以57-79％的收率提供手性苄基砜，并且具有良好或优异的对映选择性（85-95％  ee）。此外，使用2-（甲苯磺酰基甲基）芝麻酚或2-（甲苯磺酰基甲基）萘酚，可以生成稳定的o- QM底物，通过正式的[4 + 2]环加成反应可制得具有出色对映选择性的4-芳基或烷基取代的苯并二氢吡喃（ 88–97％  ee）。

  vinyl ethers 3 and o-quinone methides 2, thermally generated from 2-hydroxybenzyl alcohols 1, have been studied. The structure and conformational preferences of the 4-substituted 2-ethoxy-(2,3)-dihydro-2H-benzopyrans 4–9 obtained, which show new interesting features, are discussed together with competitive kinetic data. The cycloaddition process is concerted and involves o-quinone methides in the E-configuration

  已经研究了由2-羟基苄醇1热生成的乙烯基醚3和邻醌甲基化物2之间的环加成反应。所获得的具有新的有趣特征的4-取代的2-乙氧基-（2,3）-二氢-2H-苯并吡喃4-9的结构和构象偏好与竞争动力学数据一起进行了讨论。环加成过程是协调的，并且涉及E构型的邻醌甲基化物。对于乙基乙烯基醚和Z-1-丙烯基乙基醚，OEt-内基过渡态似乎是优选的，而对于E-1-丙烯基乙基醚，环加成过程的立体选择性取决于起始醇1的亚甲基上的取代基。这些结果以丙烯基醚甲基的内和外优先性进行讨论。
