  Semisynthesis of Fluoro-substituted Benzoates of Epi-gallocatechin

  摘要：

  In the present study, four fluoro-substituted benzoates of epi-gallocatechin (EGC) were prepared through a semisynthetic strategy, and the yield of benzylation of epigallocatechin gallate (-)-EGCG was improved by using freshly purified (-)-EGCG as starting material and a mild base of K2CO3. All structures of new compounds were characterized by H-1 NMR, C-13 NMR, high-resolution mass spectrometry, and optical rotation.
