The reaction of L-2-deoxyribose with urazole led to the formation of a single crystalline -pyranoside diastereomer, (1S,2S)- urazole -L-pyranosyl-2-deoxyriboside [IUPAC name: 1-(2-deoxy--L-erythro-pentopyranosyl) 1-(S),2-(S),4-triazolidine-3,5-dione, C7H11N3O5], which is the enantiomer of 1R,2R)-urazole -D-pyranosyl-2-deoxyriboside obtained in the analogous reaction with D-2-deoxyribose previously reported. The absolute configurations were ascertained from the known configurations of the 2-deoxyribose moieties. This is the first example of a crystalline urazole nucleoside with an L-configured sugar.
