Differentially protected 4-azido- or 4-amino-3-hydroxy-l-prolines were synthesized in good overall yields (21-31%) from d-glucose. The synthetic strategy involved conversion of d-glucose into 3-[(benzyloxycarbonyl)amino]-3- deoxy-1,2-O-isopropylidene-α-d-glucofuranose, which was subjected to mesylation of the 5- and 6-hydroxy groups and subsequent intramolecular S N2 displacement of the 6-O-mesyl group by the 3-(benzyloxycarbonyl) amino group to give a pyrrolidine ring. The resulting intermediate underwent intermolecular SN2 displacement of the 5-O-mesyl group with sodium azide, hydrolysis of 1,2-acetonide group, treatment with sodium periodate, and Pinnick oxidation to give the required compounds.
