  Acyclic cucurbit[n]urils capped with alkylene linkers: synthesis and molecular recognition properties

  摘要：

  We report the synthesis and characterization of three new acyclic cucurbit[n]uril-type receptors that feature a covalent capping group in the form of an alkylene linker (2a - 2c) that we hypothesized would have higher binding affinity toward alkylammonium ions in water. Hosts 2a - 2c have lower aqueous solubility (<= 2 mM) than the prototypical acyclic CB[n]-type host 1 (346 mM). Hosts 2a - 2c do not undergo significant intermolecular self-association over the experimentally accessible concentration range. In contrast, the results of H-1 NMR experiments shows that the alkylene linkers of 2b and 2c undergo self-inclusion and that this process is reversed upon addition of ammonium ions 6-10 as guests. The host center dot guest K-a values were determined for hosts 1 and 2a - 2c toward guests 6-10 by isothermal titration calorimetry. We find that 2a - 2c bind less strongly toward guests 6-10 than host 1 due to the energetic penalty associated with expulsion of the alkylene linker from its own cavity.[GRAPHICS].

  Here we report the first asymmetric synthesis of large chiral macrocycles with chiral sulfur atoms. Building on stereospecific SuFEx and SuPhenEx click chemistries, this approach utilizes disulfonimidoyl fluorides and disulfonimidoyl p-nitrophenolates─which are efficient building blocks with two chiral sulfur centers, and diphenols to efficiently form novel S–O bonds. Characteristic results include
