Popis:	In the present study, four fluoro-substituted benzoates of epi-gallocatechin (EGC) were prepared through a semisynthetic strategy, and the yield of benzylation of epi-gallocatechin 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 1H NMR, 13C NMR, high-resolution mass spectrometry, and optical rotation.
