Pyrrolidines 5a-b, and piperidines 10a,b and 15, were synthesised by Grignard reaction on a glycosylamine, easily obtained from the parent sugar and a primary amine, followed by cyclization with triflic anhydride.

Reaction of the commercially available 2,3,5-tri-O-benzyl-D-arabinose with a primary amine (RNH2) affords the arabinofuranosylamine 2, which on treatment with a Grignard reagent stereoselectively gives the aminoalcohol 3. 3 is an useful precursor of azasugars: it is converted into the pyrrolidine 4 by treatment with Tf2O-Py, whereas by oxidation with PCC it affords the lactam 5 which can be reduced to the corresponding amine 6.
