A new and convenient approach has been deviced for the practical synthesis of structurally robust, four different pseudoenantiomeric amino Tf-amido organocatalysts with the unique cis- and trans-substituted 1,2-cis-cyclohexanediamine structures. These pseudoenantiomeric organocatalysts are easily prepared by the Diels-Alder strategy of 2-phenyl-1,3-butadiene and maleic anhydride, and their chemical behavior was investigated by their application to asymmetric aldol synthesis for the practical synthesis of both enantiomeric aldols.

从一个常见的中间体实际合成四种具有顺式和反式取代的1,2-顺式-环己二胺结构的四种不同的假对映体有机催化剂

已经采用了一种新的方便的方法来实际合成具有独特的顺式和反式取代的1，2-顺式环己二胺结构的结构坚固的四种不同的假对映体氨基Tf-酰胺基有机催化剂。这些假对映体有机催化剂很容易通过2-苯基-1,3-丁二烯和顺丁烯二酸酐的狄尔斯-阿尔德策略制备，并且通过将其应用于不对称醇醛合成中以实际合成两种对映体醇醛来研究了它们的化学行为。
