A new strategy to effectively lock the conformation of substituents at the 3,3′-positions of axial-chiral biisoquinoline ,-dioxides was developed based on the strong dipole–dipole interaction between 1,2,3-triazole and pyridine -oxide rings. The crystal structure and the DFT calculations of 3,3′-bis(1-benzyl-1-1,2,3-triazole-4-yl)-1,1′-biisoquinoline ,-dioxide () provided strong support for this strategy
基于1,2,3-三唑和氧化吡啶环之间的强偶极-偶极相互作用,开发了一种有效锁定轴向手性双异喹啉二氧化物3,3'位取代基构象的新策略。 3,3'-bis(1-benzyl-1-1,2,3-triazyl-4-yl)-1,1'-biisoquinoline ,-dioxide ()的晶体结构和DFT计算为此提供了有力的支持。战略。此外,我们成功证明了容易获得的 4-三甲基甲硅烷基-1,2,3-三唑是用于桧山交叉偶联的可行亲核试剂。
