  A Convergent Synthesis of 14-Membered F-O-G Ring Analogs of the Teicoplanin Binding Pocket via Intramolecular SNAr Reaction

  摘要：

  An intramolecular SNAr reaction for efficient macrocyclization via biaryl ether formation was developed for syntheses of the 14-membered macrocycles 2 and 3 related to F-O-G ring of teicoplanin 1. Chloride as well as fluoride could be used as the leaving group in this reaction. However, the latter was preferred since it required milder conditions. Both ortho and para nitro, fluoro disubstituted aromatic rings were suitable for the macrocyclization reaction with tethered aryl oxides. The nonproteinogenic alpha-amino acid 23, required for the synthesis of 3, was prepared via an asymmetric Strecker synthesis using (R)-phenylglycinol as a chiral auxiliary. The overall synthetic strategy was convergent, and the cyclization could be performed in the presence of the highly sensitive arylglycine unit without racemization.

  observed in a two-component system containing a viologen-based guest and oxatub[4]arene through the involvement of the three conformers of the host. In addition, an unprecedented threading mechanism involving the tilted conformation of the guests was revealed to be responsible for the very fast kinetics and for the threading of guests with very large stoppers.
