We report herein a novel approach involving optical resolution of (±)-1,16-dihydroxytetraphenylene (DHTP) by chiral gold(iii) complexation. This method features several key advantages, , recyclability of chiral resolution reagents, feasibility of scaling up to gram quantities, and operational simplicity. On the basis of this method, which led to optically pure DHTP, a library of 2,15-diaryl ()-DHTPs and several ()-DHTP-derived phosphoramidite ligands were synthesized. Finally, the superior performance of a ()-DHTP phosphoramidite ligand was demonstrated by efficient iridium-catalyzed asymmetric allylic alkynylation reactions.
我们在此报告一种通过手性金(III)络合对(±)-1,16-二羟基四亚苯基(DHTP)进行光学拆分的新方法。该方法具有几个关键优点,即手性拆分试剂的可回收性、放大至克级的可行性以及操作简便性。基于该方法得到了光学纯的DHTP,合成了一系列2,15-二芳基()-DHTP以及几种()-DHTP衍生的亚磷酰胺配体。最后,通过高效的铱催化不对称烯丙基炔基化反应证明了()-DHTP亚磷酰胺配体的优异性能。
