Abstrakt:	Rotaxanes can serve as scaffolds for the generation of bifunctional catalysts. We have now generated acid-base functionalized rotaxanes featuring two chiral subunits. The mechanical bond leads to increased reaction rates and also to strongly altered enantioselectivites in comparison to the non-interlocked control catalysts.
