Synthesis and X-ray crystallographic investigation of N-(α-d-arabinopyranosyl)alkanamides as N-glycoprotein linkage region analogs

- Effect of pentopyranosyl structures on the N-glycosidic torsions is studied.
- Greater rotational freedom around the C1-N1 bond is seen in the arabinosyl analogs as compared to the GlcNAc derivatives.
- Glycosidic torsions are influenced by change in glycan as well as molecular packing.
- Recurrence of antiparallel bilayers in propionamido & chloroacetamido analogs is notable.
