Identification of the 2-hydroxymethyl-3,4-dihydroxypyrrolidine (or 1,4-dideoxy-1,4-iminopentitol) from and from as the (2R, 3R, 4S)-isomer by the synthesis of its enantiomer.

partial O -deacylation of fully acylated methyl glycosides and some other glycosyl compounds (23 compounds) was found to be induced, to give, in good yields, products bearing one free hydroxyl group; the results obtained indicated that, among the primary and secondary O -acyl groups, the 2- O -acyl groups were, in general, the most labile toward the nucleophile (hydrazine).
