具有仲胺和方酰胺催化单元的轮烷基有机催化剂的活化模式可以用酸或碱来切换，从三个构筑单元的混合物中得到不同的产物。具有仲胺和方酰胺催化单元的轮烷类有机催化剂的活化模式可以用酸或碱来切换。大环阻挡了它所在的任何一个催化部位。可切换轮烷催化剂根据大环环在轮烷中的位置从三个构造块的混合物中产生不同的产物。
The activation mode of a rotaxane-based organocatalyst with both secondary amine and squaramide catalytic units can be switched with acid or base, affording different products from a mixture of three building blocks. The activation mode of a rotaxane-based organocatalyst with both secondary amine and squaramide catalytic units can be switched with acid or base. The macrocycle blocks whichever of the catalytic sites it is positioned over. The switchable rotaxane catalyst generates different products from a mixture of three building blocks according to the location of the macrocyclic ring in the rotaxane.
