A simple and straightforward method for the stereocontrolled synthesis of β-linked N-glycosides uses alkyl and aryl azides as the nitrogen source. The N-glycosides are formed in high yields and with high βselectivities (typically >70 % yield, >15:1 β:α selectivity). This approach is also amenable to the synthesis of N-glycosylated amino acids and peptides (see example, Fmoc=9-fluorenylmethoxycarbonyl). Copyright
N.M.R. STUDIES OF D-RIBOSYLAMINES IN SOLUTION: DERIVATIVES OF PRIMARY AMINES

N.m.r. spectroscopy (1H, 13C) has been used to show that primary amines condense with D-ribose to give mainly D-ribopyranosylamines in which the α anomer in the 1C4 conformation preponderates; the β anomer assumes mainly the 4C1 conformation.Thus, it is possible to deduce the structures of N-phenyl-D-ribosylamines and to correlate some of the literature data.For 2,3-O-isopropylidene-D-ribofuranosylamine derivatives, the Δδ values for 13C-n.m.r. signals of the isopropylidene methyl groups can be used to establish the anomeric configuration.
