Measurements of the 1H NMR spectra of the diastereoisomers of 1-(tetrahydro-2-furanyl)-5-fluorouracil, 3-(tetrahydro-2-furanyl)-5-fluorouracil, and 1,3-bis(tetrahydro-2-furanyl)-5-fluorouracil in the presence of tris[3-(2,2,2-trifluoro-1-hydroxyethylidene)-d-camphorato]europium(Eu(TFC)3) as a chiral shift reagent showed differences between the isomers in the chemical shift changes of the protons of C2'-H and C6-H etc. 相似文献
