method using chiral N-heterocyclic carbene (NHC) as the sole organic catalyst to synthesize planarchiral carbonitriles asymmetrically, resulting in optically pure, multifunctional compounds. The method demonstrates remarkable tolerance toward diverse substituents and substitution patterns through kinetic resolution (KR) or desymmetrization processes. The resulting optically pure planarchiral products

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 asymmetriccatalysis. 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。
