摘要
Four glucosyl esters(a～d) of cinnamic acid were synthesized by the reaction of cinnamic acid with O-acetylglucopyranosyl bromide,O-acetylgalactopyranosyl bromide,O-acetylxylopyranosyl bromide and O-acetylmaltopyranosyl bromide in the presence of Bu4NBr(c and d were new compounds).Their structures were confirmed by IR,1HNMR,MS and elemental analysis.The 1HNMR and IR spectra showed that they were β-isomers.
Four glucosyl esters （a-d） of cinnamic acid were synthesized by the reaction of cinnamic acid with O- acetylglucopyranosyl bromide, O-acetylgalactopyranosyl bromide, O-acetylxylopyranosyl bromide and O- acetylmaltopyranosyl bromide in the presence of Bu4NBr（ c and d were new compounds）. Their structures were confirmed by IR, ^1HNMR,MS and elemental analysis. The ^1HNMR and IR spectra showed that they were 6- isomers.
