  Regioselective Synthesis of Antiparallel Loops on a Macrocyclic Scaffold Constrained by Oxazoles and Thiazoles

  摘要：

  [GRAPHICS]The regioselective syntheses and structures are reported for two tris-macrocylic compounds, each possessing two antiparallel loops on a macrocyclic scaffold constrained by two oxazoles and two thiazoles. NMR solution structures show the loops projecting from the same face of the macrocycle. Such molecules are shown to be prototypes for mimicking multiple loops of proteins.
