Methyl 2-azido-3-O-benzyl-2-deoxy-α-D-mamnofuranoside as a divergent intermediate for the synthesis of polyhydroxylated piperidines and pyrrolidines: synthesis of 2,5-dideoxy-2,5-imino-D-mannitol [2R,5R-dihydroxymethyl-3R,4R-dihydroxypyrrolidine

Abstract

The synthesis of methyl 2-azido-3-O-benzyl-2-deoxy-α-D-mannofuranoside (1) from D-glucose is reported; the conversions of (1) into derivatives of methyl 3-O-benzyl-2,6-dideoxy-2,6-imino-α-D-mannofuranoside (as precursors for the synthesis of polyhydroxylated piperidines) and into the hydroxylated pyrrrolidine, 2,5-dideoxy-2,5-imino-D-mannitol [2R,5R-dihydroxymethyl-3R,4R-dihydroxypyrrolidine] are described.
