D-Ribono-1,4-lactone was treated with ethylamine in DMF to afford N-ethyl-D-ribonamide 9a in quantitative yield. Bromination of amide 9a by the system SOBr 2 in DMF or PPh 3 /CBr 4 in pyridine led, after acetylation, to epoxide 7. However, treatment of amide 9a with acetyl bromide in dioxane followe
