Efficient synthesis of 2,4-dioxo-hexahydro-1,3,5-triazine O-acetyl-glycosyl glucosides and their antiviral activity
摘要:
Four 2,4-dioxohexahydro-1,3,5-triazine O-acetylglycosyl glucosides were synthesized through glucoside formation 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 beta-configuration. The results show that DMAP is an effective catalyst; the yields can reach 83.7%. The above glucosides showed an improved antiviral activity against tobacco mosaic virus.
