Carbon‐13 nuclear magnetic resonance spectra of some 2‐substituted tetrahydropyrans

Abstract

Abstract Fourier transform carbon‐13 nuclear magnetic resonance spectra have been obtained and interpreted for some 2‐substituted tetrahydropyrans. The effects of the substituents on α, β, γ and δ‐carbon atoms are discussed. Using suitable reference compounds the γ‐parameter can be used for quantitative conformational analysis.
