  Dynamic Chirality in Donor−Acceptor Pretzelanes

  摘要：

  A series of donor-acceptor pretzelanes has been synthesized, using self-assembly and template-directed protocols, and the dynamic processes that these pretzelanes undergo have been investigated in solution. These compounds exist as libraries of diastereoisomers as a result of their multiple stereoelements, which are dynamically interconverted by several different, in some cases competing, processes. Altering the structure of the pretzelanes changes the rates and mechanisms by which these diastereoisomers equilibrate. Additionally, inserting an element of fixed chirality allows the equilibrium to be biased, while maintaining the barrier to the equilibration processes. These results bode well for the future construction of molecular devices based on switchable diastereoisomerism involving metastable states.

  Coordination of a carboxylic acid diaryl crown ether to a Sn(IV) porphyrin promotes its ability to act as a template for the formation of a [2]catenane: in the absence of the porphyrin the acid-crown yields only a tiny amount of the interlocked derivative, Once isolated the free acid-[2]catenane presents extremely broad resonances in its 500 MHz H-1 NMR spectrum, but complexation to a Sn(IV) porphyrin results in dramatic resolution via a combination of dynamic and dispersive effects.
