Abstract
The infrared study of the solvent effect on D-glycero-pent-2-enopyranosides (α and β) that can be used as substrate precursors in the synthesis of antibiotic ristomycin components, is reported. The higher energy content in α anomers justifies differences in intra- and interbonding with respect to β anomers of the OH and the CO moieties. This behaviour is confirmed by the analysis of half band width values in different solvent mixtures. The pronounced γC(2)-H band found only in α derivatives, makes this vibrational mode of a diagnostic importance in the assignment of the configuration.
