✦ Synopsis


A practical synthesis of 2-deoxy-L-ribose from L-arabinose depends on the efficient reduction by iodide of a triflate a to a lactone. The X-ray crystal structure of 3,4-O-isopropylidene-L-arabinono-1,5-lactone is reported.

Interconversion of the ends of D-ribese 2 afforded in 6 steps and 45% overall yield L-ribose 1, from which 2-deoxy L-ribose 12 was easily prepared. In addition, the inexpensive L-arabinose 13 was also converted into 2-deoxy L-ribose 12 via a reductive radical rearrangement of the arabinopyranosyl br

The relative configuration at C-2 of 2,4-dimethyl-3,4-__O__-isopropylidene-L-arabinono lactone, C~10~H~16~O~5~, which exists in the boat form, was unequivocally established by X-ray crystallographic analysis. The absolute configuration was determined by the use of 2-__C__-methyl-D-ribonolactone as a
