Jf. Espinosa et al., Conformational differences between C- and O-glycosides: The alpha-C-mannobiose/alpha-O-mannobiose case, CHEM-EUR J, 5(2), 1999, pp. 442-448
The conformational behavior of methyl alpha-C-mannobiose (1) and an analogu
e 3 bearing a hydroxy group at the bridging position have been studied with
a combination of NMR spectroscopy (J and NOE data) in different solvents a
nd molecular mechanics and dynamics calculations. The obtained results show
clear differences with respect to the O-disaccharide analogue 2.
