expected 6-deoxy derivative, the (acyclic) 5-enoalditol. The synthesis of 44 was conducted via 2,5-anhydro-1,6-di-O-tosyl- d -mannitol (36), which was obtained from 1,6-di-O-benzoyl-3,4-O-isopropylidene- d -mannitol in satisfactory yield. Ditosylate 36 was converted into a 2,5:3,6-dianhydro monotosylate which, on reduction with lithium aluminum hydride, gave the 1-deoxy derivative. Opening of the 3
