family of [2.2]paracyclophane derivatives is described. Different substituted pyrazole, triazole and pyrimidine moieties were introduced to the [2.2]paracyclophane scaffold and the products were characterized spectroscopically and by X-ray structure analysis. These compounds are promising ligands for application in asymmetric catalysis. We show here that one of these ligands can catalyze asymmetric conjugate
描述了一个新的 [2.2] 对环芳烷衍生物家族。将不同取代的吡唑、三唑和嘧啶部分引入 [2.2] 对环芳烃支架,并通过光谱和 X 射线结构分析对产物进行表征。这些化合物是用于不对称催化的有前途的配体。我们在这里展示了这些配体之一可以催化不对称共轭加成。此外,通过使用羟基-吡唑基[2.2]对环芳烷配体合成了钯配合物。
