  Nucleophilic addition of TMSCCl3 to N-phosphinoyl benzaldimines: a route to N-phosphinoyl-α-(trichloromethyl)benzylamines

  摘要：

  Nucleophilic addition of readily available TNISCCl3 to N-phosphinoyl benzaldimines allows preparation of N-phosphinoyl-alpha-(trichloromethyl)benzylamines. Typically, the reaction in THF at room temperature using tetrabutylammonium difluorotriphenylsilicate (TBAT) as a catalytic promoter, afforded very good yields (65-95% range) for most derivatives within 1 h at room temperature.

  the acylsilane compared to the imine allows the direct mixing of all the reagents in a three-component, one-pot process. A methodology allowing the direct preparation of β-amino-α,α-difluoroketones from the Ruppert–Prakash reagent (CF3TMS), acyltrimethylsilanes and N-Boc or N-(diphenylphosphinyl)imines is reported. The process, initiated by a catalytic amount of tetra-n-butylammonium difluorotriphenylsilicate

  Full details of a direct catalytic asymmetric Mannich-type reaction of a hydroxyketone using a Et2Zn/(S,S)-linked-BINOL complex are described. By choosing the proper protective groups on imine nitrogen, either anti- or syn-beta-amino alcohol was obtained in good diastereomeric ratio, yield, and excellent enantiomeric excess using the same zinc catalysis. N-Diphenylphosphinoyl (Dpp) imine 3 gave anti-beta-amino

  描述了使用 Et2Zn/(S,S) 连接的 BINOL 复合物对羟基酮进行直接催化不对称曼尼希型反应的全部细节。通过在亚胺氮上选择适当的保护基团，使用相同的锌催化，可以以良好的非对映体比例、产率和优异的对映体过量获得反-或顺-β-氨基醇。N-二苯基膦酰基 (Dpp) 亚胺 3 以 anti/syn = 高达 >98/2、高达 >99% 的收率和高达 >99.5% 的 ee 得到抗 β-氨基醇，而 Boc-亚胺 4 得到了合成- anti/syn 中的 β-氨基醇 = 高达 5/95，高达 >99% 的产率和高达 >99.5% 的 ee。高催化剂周转数 (TON) 也值得注意。对于反选择性反应，催化剂负载成功地减少到 0.02 mol %（TON = 高达 4920），对于顺选择性反应，催化剂负载减少到 0.05 mol %（TON = 高达 1760）。Et2Zn/(S,S)-linked-BINOL
• The Amino Thiourea-Catalyzed Asymmetric Nucleophilic Reactions

  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。
