Abstract

Heterobifunctional class="Chemical">rotaxanes serve as efficieclass="Chemical">nt catalysts for the additioclass="Chemical">n of class="Chemical">n class="Chemical">malonates to Michael acceptors. We report a series of four different heterobifunctional rotaxanes, featuring an amine-based thread and a chiral 1,1'-binaphthyl-phosphoric-acid-based macrocycle. High-level DFT calculations provided mechanistic insights and enabled rational catalyst improvements, leading to interlocked catalysts that surpass their non-interlocked counterparts in terms of reaction rates and stereoselectivities.
