Synthesis of a novel secondary dialkylammonium salt with three stations and its threading through the cavity of two crown ethers

In this paper, a novel secondary dialkylammonium salt with three stations (G1) was synthesized in 5 steps. 1H NMR was used to study the threading of G1 through the cavity of dibenzo-24-crown-8 (DB24C8) and benzo-21-crown-7

Self-Assembling - and Rotaxanes from Secondary Dialkylammonium Salts and Crown Ethers

The self-assembly of three new rotaxanes - two rotaxanes and a rotaxane - formed by a "threading followed by stoppering" approach is described.These template-directed syntheses rely on the formation of pseudorotaxane intermediates, which self-assemble in solution from functionalized secondary dialkylammonium hexafluorophosphate threads and macrocyclic polyether rings (either dibenzocrown-8 or its asymmetric constitutional isomer).The stoppers - substituted 1,2,3-triazoles - were created by thermally allowed 1,3-dipolar cycloaddition between azido groups, which terminate the threads, and di-tert-butyl acetylenedicarboxylate. - Keywords: interlocking molecules; molecular recognition; pseudorotaxanes; rotaxanes; template syntheses
