外文摘要：Six benzimidazolylphenoxyacetic acid O-acetylxylopyranosyl and O-acetylgalactopyranosyl esters were synthesized through esterification reactions at room temperature using 4-dimethylaminopyridine as a catalyst and triethylamine as a deacidification reagent. Their structure was confirmed by IR, H-1 NMR spectra, MS, and elemental analysis. The synthesized compounds are all of P-configuration. The results show that DMAP is an effective catalyst; the yields can reach 63.6%. The above esters showed an improved antiviral activity against tobacco mosaic virus.
