  One-Pot Formation of Aromatic Tetraurea Macrocycles

  摘要：

  Treating derivatives of m-phenylenediamine having different electron-richness and reactivities with triphosgene in the presence of triethylamine led to aromatic tetraurea rnacrocycles in high yields. Factors important for efficiently forming these macrocycles include the molar ratio (2:1) between the diamine and triphosgene, reaction temperature (-75 degrees C), and solvent (CH2Cl2). By controlling the order and rate for adding diamines, tetraurea macrocycles consisting of two different types of monomeric residues have also been obtained in high yields.

• Hydrogen Bonding-Directed Multicomponent Dynamic Covalent Assembly of Mono- and Bimacrocycles. Self-Sorting and Macrocycle Exchange

  This paper describes the multicomponent dynamic covalent assembly of macrocyclic structures by utilizing hydrogen bonding-driven zigzag anthranilamides as "leading" components. Two or three amino groups have been introduced to one side of hydrogen bonded anthranilamide oligomers. The preorganization of the frameworks enabled the amino groups to condense with structurally matched aldehydes to form mono- and bimacrocycles in good to quantitative yields. Reactions from Lip to five components have been investigated. which involved one-step formation of up to six imine bonds. The preorganization of the templates highly enhanced the stability of the macrocyclic structures. As a result, all the macrocycles Could be purified by simply recrystallizing the Crude products from suitable solvents. Coexisting experiments of three series of three to five components were also performed, which all revealed that the preorganized precursors possessed high self-sorting capacity. On the basis of the same approach, a hydrazone-based macrocycle was also prepared quantitatively, while an intermacrocycle hydrazone-imine exchange was revealed to facilitate the formation of the hydrazone-based macrocycle from an imine-based macrocycle.
• Helical Folding of <i>Meta</i>-Connected Aromatic Oligoureas

  Aromatic oligoureas composed of meta-linked residues bearing phenolic ether side chains are synthesized. The basic N,N '-diarylurea units adopt a trans,trans intramolecularly H-bonded conformation that is further strengthened by additional intermolecular H-bonding. Such basic units, in combination with meta-linked benzene residues, result in stably folded helical oligoureas in the highly polar DMF with up to four turns and with a small cylindrical inner pore that would be difficult to acquire.
