  用于不对称直接曼尼希型反应的高度实用的BINOL衍生酸基复合盐催化剂

  摘要：

  亚胺和1，3-二羰基化合物之间的催化不对称直接曼尼希型反应是有机化学中最重要的碳-碳键形成反应之一。所得的曼尼希加合物可以有效地转化为药学上有用的旋光性β-氨基酮，β-氨基酯，β-内酰胺等。在我们研究用于不对称反应的手性酸-碱结合盐催化剂的过程中，我们开发了一系列简单，实用的手性BINOL衍生的盐催化剂，例如手性吡啶鎓1,1'-联萘-2,2'-二磺酸盐1，手性联萘甲酸锂（I）2，手性联萘甲酸镁（II）（3） ，手性磷酸钙（II）4和手性磷酸5，对直接曼尼希型反应特别有效。 1引言 2 1,1'-联萘-2,2'-二磺酸（BINSA）-吡啶鎓盐 3萘甲酸锂（I）盐 4萘甲酸镁（II）盐 5磷酸钙（II）盐和手性磷酸 6。结论 酸碱复合盐催化剂-亚胺-不对称催化-1,3-二羰基化合物-直接曼尼希型反应

  Hexamethylphosphoramide (HMPA) was added to a reaction vessel containing (R)-1,1'-binaphthyl-2,2'-dithiol and potassium hydroxide. The vessel was purged with oxygen and stirred at 80°C for 5 days under 7 atmospheres of oxygen. After being cooled to room temperature, the reaction product was purified to yield potassium (R)-1,1'-binaphthyl-2,2'-disulfonate. The (R)-1,1'-binaphthyl-2,2'-disulfonic acid obtained from the disulfonate and 2,6-diphenylpyridine were stirred in acetonitrile, and then the solvent was evaporated under reduced pressure. Subsequently, magnesium sulfate and distilled CH2Cl2 were added to the reaction product, and the mixture was stirred at room temperature for 30 minutes. The resulting solution was cooled to 0°C. Benzaldehyde imine whose nitrogen is protected with Cbz and subsequently acetyl acetone were dropped into the solution over a period of 1 hour. The resulting mixture was further stirred at 0°C for 30 minutes. A corresponding β-aminocarbonyl derivative was thus produced with an yield of 91% and an enantiomeric excess of 90% ee.
