is presented. Significantly, the protocol facilitated the smooth participation of sterically hindered and protecting group free 2-bromobenzyl tertiary alcohols in cross coupling reactions with phenols and anilines, under copper-catalysis. The Lewis acid mediated intramolecular C–C bond formation enabled the formation of a quaternary carbon atom at the 9th-position. Remarkably, this two-step protocol
                                    一种用于呫吨和含在一个9季碳原子dihydroacridines的合成简单和有效的方法个位上,被呈现。重要的是,在
铜催化下,该方案促进了空间位阻和保护基的2-
溴苄基叔醇在与
苯酚和
苯胺的交叉偶联反应中的平稳参与。介导的分子内的C-C键形成的
路易斯酸启用一个季碳原子的形成在9个位上。值得注意的是,此两步操作方案需要单柱纯化技术。
