  Enantioselective Cyclization of Racemic Supramolecular Polymers

  摘要：

  Homochiral hydrogen-bonded cyclic assemblies are formed in dilute solutions of racemic supramolecular polymers based on the quadruple hydrogen bonding 2-ureido-4[1H]-pyrimidinone unit, as observed by 1H NMR and SEC experiments. Preorganization of the monomers and the combined binding strength of the eight hydrogen bonds result in a very high stability of the cyclic aggregates with pronounced selectivity between homochiral and heterochiral cyclic species, usually only observed in crystalline or liquid crystalline phases.

  A method is provided for the direct synthesis of novel polymeric materials functionalized with desirable nitrogen-containing functional groups such as terminal azido, cuano, carbonylamino or thiocarbonylamino groups. Polymerization and functionalization occur in a substantially simultaneous manner. All necessary reactants for the functionalization are present when polymerization is initiated. The nitrogen-containing functional group is provided as a part of a molecule having a release moiety which is preferably resonance stabilized or of tertiary alkyl type and which acts to aid the nitrogen-containing species in functioning as a leaving group.

  本发明提供了一种直接合成新型聚合物材料的方法，该材料具有理想的含氮官能团，如末端叠氮基、氨基、羰基氨基或硫代羰基氨基。聚合和官能化基本上是同时进行的。聚合开始时，官能化所需的所有反应物都已存在。含氮官能团是作为分子的一部分提供的，该分子具有释放基，释放基最好是共振稳定的或叔烷基类型的，其作用是帮助含氮物质作为离去基团发挥作用。
