The axial chirality of carbodiimide was proposed in 1932, but the synthesis of carbodiimide with one-handed axial chirality has not been achieved because of the low barrier of racemization. This work presents a strategy to use a conformationally restrained cyclic structure for creating carbodiimides whose biases of the axial chirality (labeled as SNCN/ RNCN) are higher than 100:1, as determined by
碳二亚胺的轴向手性是在1932年提出的,但由于外消旋化的障碍低,尚未实现单手轴向手性的碳二亚胺的合成。这项工作提出了一种使用构象约束环状结构来制造碳二亚胺的策略,其轴向手性偏差(标记为 SNCN/RNCN)高于 100:1,由振动圆二色光谱和密度泛函理论计算确定。
