A C-linked glycomimetic in the gas phase and in solution: synthesis and conformation of the disaccharide Manalpha(1,6)-C-ManalphaOPh.
The effect of carbon is subtle but sweet: The flexible C-linkage in the newly synthesised C-glycosyl mimetic, Manalpha(1,6)-C-ManalphaOPh allows OH--pi bonding, both in the gas phase and in aqueous solution. This interaction is absent in the O-linked disaccharide (see figure).The intrinsic conformational preference of a newly synthesised glycomimetic, the C-linked disaccharide Manalpha(1,6)-C-ManalphaOPh (1), has been determined in the gas phase at about 10 K by infrared ion dip spectroscopy ...Expand abstract
