  N-Propargylamides via the Asymmetric Michael Addition of B-Alkynyl-10-TMS-9- borabicyclo[3.3.2]decanes to N-Acylimines

  摘要：

  The asymmetric synthesis of N-propargylamides through Michael addition of the alkynylborane 1 to N-acylimines is reported. The N-acetylimines provide the best substrates for the process exhibiting high selectivity (56-95% ee) with predictable stereochemistry. In several cases, 5 crystallizes in essentially pure form (97-99% ee) and a single-crystal X-ray structure was also obtained for 5g (R-1 = R-2 = Me, R-3 = o-Cl-C6C4). The process regenerates 4 for its direct conversion back to 1 and facilitates the efficient recovery of the pseudoephedrine.

• The Amino Thiourea-Catalyzed Asymmetric Nucleophilic Reactions
  作者：Yoshiji Takemoto、Hideto Miyabe

  DOI：10.2533/chimia.2007.269

  日期：——

  Bifunctional amino thiourea-catalyzed asymmetric additions of several nucleophiles into electron-deficient unsaturated compounds such as nitroolefins, ?,?-unsaturated imides, imines, and azodicarboxylates are described. We discovered that bifunctional thioureas bearing a tertiary amino group significantly accelerated several nucleophilic addition reactions of active methylene compounds to electron-deficient double bonds. In these reactions, a strong hydrogen-bonding ability of the thiourea moiety as well as an appropriate Brønsted basicity of the tertiary amine is crucial for high enantioselectivity. This dual activation of both nucleophiles and electrophiles by the bifunctional thiourea expanded the applicability of the thiourea-catalyzed enantioselective reaction. In addition, these organocatalyzed asymmetric reactions were successfully applied to the concise asymmetric synthesis of natural products and medicinal candidates such as epibatidine, baclofen, and CP-99,994.

  双功能氨基硫脲催化的不对称加成反应将几种亲核试剂加入到电子不足的不饱和化合物中，如硝基烯烃、α，β-不饱和亚酰胺、亚胺和叠氮二羧酸酯。我们发现，含有三级胺基的双功能硫脲显著加速了活性亚甲基化合物与电子不足双键的几种亲核加成反应。在这些反应中，硫脲基团的强氢键能力以及三级胺的适当Brønsted碱性对高对映选择性至关重要。双功能硫脲对亲核试剂和电子亲电试剂的双重活化扩展了硫脲催化的不对称反应的适用范围。此外，这些有机催化的不对称反应成功应用于天然产物和药用候选化合物的简洁不对称合成，如蛙毒碱、氯硝西泮和CP-99,994。

  is directly applied to the synthesis of Maraviroc, the selective CCR5 antagonist with potent activity against HIV-1 infection. Mechanistic investigations of the allylboration reaction including IR, NMR, and mass spectrometry studies indicate that acyclic boronates are activated by chiral diols via exchange of one of the boronate alkoxy groups with activation of the acyl imine via hydrogen bonding.

  Corrosion-inhibiting pigments based on manganese are described that contain a trivalent or tetravalent manganese/valence stabilizer complex. An inorganic or organic material is used to stabilize the trivalent or tetravalent manganese ion to form a compound that is sparingly soluble, exhibits low solubility, or is insoluble in water, depending upon the intended usage. Specific stabilizers are chosen to control the release rate of trivalent or tetravalent manganese during exposure to water and to tailor the compatibility of the powder when used as a pigment in a chosen binder system. Stabilizers may also modify the processing and handling characteristics of the formed powders. Manganese/valence stabilizer combinations are chosen based on the well-founded principles of manganese coordination chemistry. Many manganese-valence stabilizer combinations are presented that can equal the performance of conventional hexavalent chromium or tetravalent lead systems. It is emphasized that this abstract is provided to comply with the rules requiring an abstract which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.

  A corrosion-inhibiting pigment comprising a rare earth element and a valence stabilizer combinded to form a rare earth/valence stabilizer complex. The rare earth element is selected from cerium, terbium, praseodymium, or a combination thereof, and at least one rare earth element is in the tetravalent oxidation state. An inorganic or organic material is used to stabilize the tetravalent rare earth ion to form a compound that is sparingly soluble in water. Specific stabilizers are chosen to control the release rate of tetravalent cerium, terbium, or praseodymium during exposure to water and to tailor the compatibility of the powder when used as a pigment in a chosen binder system. Stabilizers may also modify the processing and handling characteristics of the formed powders. Many rare earth-valence stabilizer combinations are presented that can equal the performance of conventional hexavalent chromium systems.

  Alkynylboronates derived from 3,3'-disubstituted-2,2'-binaphthols react with various N-acylimines to give the expected chiral propargylamides with up to 99% ee. This new methodology was applied to the first enantioselective synthesis of the antitubulin agent (-)-N-acetylcolchinol.
