A strategy towards the synthesis of three different target molecules, namely 1,4-dideoxy-1,4-imino-L-xylitol, deacetyl (+)-anisomycin and amino-substituted piperidine iminosugars, molecules of potential biological and medicinal significance, is reported from a common amino-vicinal diol intermediate derived from tri-O-benzyl-D-glucal. Construction of the key pyrrolidine ring present in 1,4-dideoxy-1,4-imino-L-xylitol and (+)-anisomycin was a consequence of thermodynamically driven concomitant intramolecular nucleophilic addition reaction of the amino group to the resultant aldehyde obtained by oxidative cleavage of the amino-vicinal diol. Alternatively, double nucleophilic substitution on an amino-diol, after mesylation, with various amines delivered amino-substituted piperidine iminosugars in good yields.

An efficient approach to enantiomerically pure (+)-deacetylanisomycin 2a and a formal synthesis of (+)-anisomycin 2 (11% overall yield in 10 steps) have been achieved through simple and good yielding reactions, starting from 1,2:3,4:5,6-tri-O-isopropylidene-D-mannitol 3. Grignard reaction and intramolecular cyclisation reactions are key steps in the strategy.

A stereoselective synthesis of (-)-deacetylanisomycin has been achieved from a nitrone derived from 1-threose in 6 steps and 53.7% overall yield, The key step of the synthesis is the nucleophilic addition of a Grignard derivative with complete diastereofacial selectivity.
