  The Role of theα-Stereogenic Center in the Control of Stereoselection in the Reduction ofα-Alkyl-β-hydroxy Ketones: A Highly Diastereoselective Protocol for the Synthesis of 1,2-syn-2-Alkyl-1,3-diols

  摘要：

  Accurate investigations on the role played by an alpha-stereogenic center in controlling the reduction of various classes of beta-hydroxy ketones allowed us to set up a general and highly diastereoselective protocol for the synthesis of 2-alkyl-1,3-diols with 1,2-syn relationship. This methodology is based on the conversion of a beta-hydroxy ketone into the corresponding titanium alcoholate that permits us to organize the substrate in a stable and rigid structure, which stereofacially favors attacking hydride ions. The use of THF as solvent makes available a variety of hydride donors that cover a large spectrum of steric demand: the choice of the more appropriate one depends on the conformational stability of the cyclic intermediate. Excellent results are obtained also in the presence of an additional stereogenic center in the beta-position, even if it exerts a concordant or an opposite steric effect with respect to the alpha-substituent.

  通过由α-碘酮和9-硼双环[3.3.1]壬烷生成的硼烯醇化物进行立体选择性交叉羟醛反应

  摘要：

  硼烯醇化物是通过处理各种 α-碘酮如 2-iodo-1-phenylpropan-1-one、2-iodo-1-(4-methoxyphenyl)propan-1-one、2-iodopentan- 3-one, 2-iodo-2-methyl-1-phenylpropan-1-one, 3,4-dihydro-2-iodo-1(2H)-naphthalenone, 2-iodo-1-phenylethan-1-one 和 1 -iodo-4-phenylbutan-2-one 与 9-borabicyclo[3.3.1]nonane (9-BBN)。通过由此形成的硼烯醇化物与各种醛的后续反应，以良好的收率和良好至高的非对映选择性生产了羟醛。通过蒸馏成功分离了几种衍生自 α-碘酮和频哪醇硼烷的硼烯醇化物，但产率相当适中。

  A highly diastereoselective cross aldol reaction is developed using divalent tin enolates formed from stannous trifluoromethanesulfonate and carbonyl compounds. The reaction is extended to a highly enantioselective cross aldol reaction employing chiral diamines derived from (S)-proline as ligands.

  AcOLi catalyst, the aldol reaction in water-containing DMF was studied in detail. AcOLi and various metal carboxylates behaved as effective Lewis base catalysts in aldol reactions between trimethylsilyl enolate and aldehydes in DMF-H 2 O (50:1) (Tables 6, 7). One of the most characteristic points of the above reaction that took place in water-containing DMF is that the aldehydes having a free amide

  complexes have been prepared and used for isomerization of allylic alcohols to the corresponding saturated carbonyl compounds. Complexes bearing CO ligands show higher activity than those with PPh3 ligands. The isomerization rate is highly affected by the substituents on the Cp ring. Tetra(phenyl)methyl-substituted catalysts rapidly isomerize allylic alcohols under very mild reaction conditions (ambient

  已经制备了多种钌环戊二烯基（Cp）配合物，并将其用于烯丙基醇异构化为相应的饱和羰基化合物。带有CO配体的配合物显示出比具有PPh3配体的配合物更高的活性。异构化速率受Cp环上的取代基影响很大。四（苯基）甲基取代的催化剂可在非常温和的反应条件下（环境温度）以短的反应时间快速异构化烯丙醇。取代的烯丙醇已经通过使用Ru-Cp络合物被异构化。对[Ru（Ph5Cp）（CO）2H]（14）催化的异构化的研究表明，氢化钌催化的异构化部分与KOtBu活化的卤化钌的催化机理不同。此外，

  Trichlorosilyl enolates of ketones (enoxytrichlorosilanes) were demonstrated to be highly reactive aldol addition reagents. Trichlorosilyl enolates of cyclohexanone (E-enolate) and propiophenone (Z-enolate) reacted readily at room temperature with a wide variety of aldehydes to afford aldol addition products in high yield and diastereoselectivity (E → syn, Z → anti). These reactions were shown to be

  酮的三氯甲硅烷基烯醇化物（烯氧基三氯硅烷）被证明是高度反应性的羟醛加成试剂。环己酮（E-烯醇化物）和苯丙酮（Z-烯醇化物）的三氯甲硅烷基烯醇化物在室温下很容易与多种醛反应，以高产率和非对映选择性（E→syn，Z→anti）得到羟醛加成产物。这些反应被证明对催化量的手性磷酰胺的加速非常敏感。特别是，衍生自 (S,S)-芪二胺的磷酰胺不仅在加速反应方面显着有效，而且在调节非对映选择性和提供具有良好至优异对映选择性的羟醛加成产物方面也非常有效。未促进过程的非对映选择性已被解释为通过五配位、三角双锥 (tbp) 硅配合物通过船状过渡结构进行反应的结果。磷酰胺催化的反应更复杂，...
