Concise synthesis of the tris(pyrimidones) 1a,b is described. Molecular modeling study demonstrated that both the prepared models 1a,b are capable of self-assembling under formation of spherical dimers locked by 18 hydrogen bonds. Extreme insolubility in all common solvents precluded investigation of the self-assembly in solution. Circumstantial evidence in favor of the self-assembly has been provided in the solid and gas phase.
描述了三(嘧啶酮)1a,b的简明合成。分子建模研究表明,所制备的模型1a,b都能够在形成由18个氢键锁定的球形二聚体的情况下自组装。在所有常见溶剂中的极端不溶性阻止了对溶液中自组装的研究。在固态和气相中提供了支持自组装的间接证据。
