A wide variety of 2-methyl-resorcinol-based deepened cavitands were synthesised from readily available reagents in a four-step procedure with overall yields of up to 62%. A systematic variation of the rim was carried out by building up a flexible upper aromatic wall on the rigid cavitand platform through CH2, CH2O and CH2OCH2 spacers. These aromatic walls were further extended by a Suzuki cross-coupling
多种基于 2-甲基
间苯二酚的深空腔是由现成的试剂通过四步程序合成的,总产率高达 62%。通过在刚性空腔平台上通过
CH2、 O 和 O 间隔物构建柔性上芳香壁,进行了轮辋的系统变化。这些芳香壁通过铃木交叉偶联反应进一步扩展。对合成的空腔进行了全面表征。四(苯氧基甲基)腔的固态结构由 X 射线晶体学确定。该分子的气相理论计算预测上苯环之间存在弱的 T 型相互作用。
