  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.

  A series of novel stilbene derivatives has been synthesized and studied with the main goal to investigate SAR of the amino compound 1a, as well as to improve its water solubility, a potentially negative aspect of the molecule that could be a serious obstacle for a pre-clinical development. We have obtained derivatives with good cytotoxic activity, in particular, the derivatives 5c and 6b could represent two novel leads for further investigation. Compound 8b, a morpholino-carbamate derivative, prodrug of 1a, has a very good solubility in water, and is active in suppressing growth of tumor cells at a concentration of 5000 nM, which is a concentration 100 times higher than the parent stilbene 1a.
