A series of thermally stable atropisomeric phencyclone ligands (ΔG‡rac > 35 kcal mol−1), bearing two chiral axes, has been successfully synthesized, taking into account the results of DFT calculations on model systems. The absolute configurations of the novel atropisomers have been assigned using TD-DFT simulation of ECD spectra. Atropisomeric phencyclones herein presented pave the way towards new
考虑到模型系统的DFT计算结果,已经成功合成了一系列带有两个手性轴的热稳定的阻转异构苯环酮配体(ΔG ‡ rac > 35 kcal mol -1)。新型阻转异构体的绝对构型已使用ECD光谱的TD-DFT模拟进行了分配。本文提出的对映异构体苯环酮为新的基于钌的对映选择性氢化催化剂铺平了道路。
