Abstract: | 1-(5-Halo-1-uracilyl)-2, 5-di-O-acetyl- -D-glucofuranurono-6,3-lactones were obtained by condensation of 2,4-bis(trimethylsilyl)-5-halouracils with 1,2,5-tri-O-acetyl- -D-glucofuranurono;-6, 3-lactone. The chemical transformations of these compounds were studied. The structure of the glucuronides was proved by the IR, UV, circular dichroism, and NMR spectra.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 11, pp. 1532–1537, November, 1981. |
