Resumen:
We have reported the synthesis of deoxy1.2 and dideoxy3,4 sugars v¨ªa B-elimination reactions ocurring on benzolatyon of aldonolactones. Recently, we described the preparation of Ascarylose3 (3,6-dideoxy-L-arabino-hexose) and a crystalline, furanoid benzoate of this sugar, starting from L-rhamnono-1,5-lactone. We now report that double elimination was observed when L-rhamnono-1,4-lactone was benzoylated under similar conditions. The unsaturated lactone derivative was used for the synthesis of 2-O-benzoyl-3,5,6-trideoxy-¦Á-DL-threo-hexofuranose.
