    13C NMR spectra of 5β,14β-hydroxysteroidsPresented at the 4th North German NMR Meeting, Braänschweig, 10 May 1985. (1985)
    Chichester : Wiley-Blackwell
    Organic Magnetic Resonance 23 (1985), S. 959-963

    Notes: The 13C chemical shifts of 30 substituted 5β,14β-hydroxysteroids are described and discussed. Substituent chemical shifts for 12α- and 12β-hydroxy groups were evaluated, and interesting γ effects were observed. A correlation is shown to exist between the 1H shifts of H-17 and the 13C shifts of C-17 for various C-12 substituents. A relationship for the distance of the substituent at C-12 from H-17 in the 14β,20-lactones was demonstrated, where an increased distance between these atoms is associated with smaller shift differences.
