Abstract: Several benzoyl esters of (+)-catechin [(2R,3S)-2-(3,4-dihydroxyphenyl)-3,4-dihydro-2H-benzo[b]-pyran-3,5,7-triol] have been synthesized by the dicyclohexylcarbodiimide promoted condensation of (+)-catechin hydroxy groups with benzoic acid. All the products were identified by MS, ¹H  and ¹³C  NMR spectroscopy. The determination of the esterification position was carried out by long-range INEPT pulse sequence.
