本研究描述了四丁基铵盐(TBAX)在氢键大环芳香族五聚体中,在类似的化学微环境中,通过有效的单脱甲基或双脱甲基来去除五个芳香族甲氧基甲基中的一个或两个的能力。这些去甲基化被发现既是化学选择性的,也是区域选择性的,并由大环主干的氢键定向折叠促进。
Described in this study is the ability of tetrabutylammonium salts (TBAX) to mediate an efficient mono- or di-demethylation removing one or two out of five aromatic methoxy methyl groups situated in similar chemical microenvironments in a H-bonded macrocyclic aromatic pentamer. These demethylations are found to be both chemo- and regioselective, and promoted by the H-bonding directed folding of the macrocyclic backbone.
