摘要：

Natural-abundance 13C-n.m.r. spectra of seven di- and tri-O-(3-nitropropanoyl)-α- and -β-d-glucopyranoses are reported and discussed. Linear regression-analysis of the extracted 13C-substituted parameters associated with esterification at various positions of the α- and β-glucose skeletons yielded two sets of substituent chemical-shift constants. The chemical shifts calculated from these generated parameters agreed well with the experimentally obtained values for each compound. Additivity of the substituent-induced shifts as a function of esterification site and substituent orientation is discussed. The structures of three previously uncharacterized di- and tri-esters were ascertained by using the parameters established. © 1979.
