  A cyclic trimer of 2-(2-aminophenoxy)propionic acid with a bowl-shaped structure

  摘要：

  A cyclic trimer of (R)-2-(2-aminophenoxy)propanoic acid, a delta-amino acid analogue, was synthesized. Molecular mechanics calculations on the cyclic trimer predicted that a concave network of sequential hydrogen bonds forms a C(3)-symmetric bowl-shaped structure. Evidence for this conformation was found in the NMR spectra of the trimer in D-chloroform. Although the single-crystal structure of the cyclic trimer indicates that chloroform could be included in the bowl-shaped structure, the conformation was not C(3)-symmetric and the hydrogen bonding network was of a different mode. These different conformations between solid and Solution were reasonably clear from IR spectra. (C) 2009 Elsevier Ltd. All Fights reserved.
