  C-Nucleosides. 21. Synthesis of Isoxazole C-Nucleoside from Furanone Glycoside via Enaminone Glycoside

  摘要：

  Synthesis of the versatile and stable C-nucleoside precursor enaminone glycosides (3a,b) was achieved by reaction of furanone glycoside (1) with 2- and 4-aminophenols. Treatment of enaminone (3b) with hydroxylamine hydrochloride yielded 5-hydroxy-4,5-dihydroisoxazole(5), which on dehydration with toluene-p-sulfonic acid in benzene gave 5-(2,3,5-tri-O-benzoyl-beta-D-ribofuranosyl)isoxazole (6). Deblocking of compound (6) with sodium carbonate gave 5-(beta-D-ribofuranosyl)isoxazole (7).

  Abstract The synthesis of 3-β- d -ribofuranosyl-1 H -pyrazole-4-carboxamide ( 11 ) is described. Treatment of enaminone glycoside 1 with trimethyl orthoformate afforded the aldehyde 2 . The aldehyde 2 was oximated with hydroxylamine. Oxime 3 was cyclized with hydrazine to afford the pyrazole 8 . The pyrazole 8 was dehydrated with acetic anhydride, and the nitrile 9 was treated with nickel acetate in acetic
