Carbon-13 NMR spectra of saturated heterocycles: VIII—tetrahydrofurans and 1,3-dioxolanes
Authors:Ernest L Eliel  V Satyanarayana Rao  K Michal Pietrusiewicz
Abstract:The 13C NMR spectra of 17 methyl- and ethyl-substituted tetrahydrofurans and 58 alkyl- and aryl- substituted 1,3-dioxolanes are reported. For the cases in which substituents recur, additive substituent parameters are calculated and compared with similar parameters in cyclopentanes and in 6-membered rings. Considering the conformational flexibility of 5-membered ring systems, additivity of the parameters is surprisingly good.
