Notes:
Carbon-13 NMR signals were assigned to a set of methyl 5β-cholanoates having multiple functional groups, including hydroxy, carbonyl and acetoxy groups. Assignments were based on empirical chemical shift rules for α-, β- and γ-substituent effects, direct spectral comparison with compounds of similar structure, DEPT and 2D-HETCOR. Use of β-substituent effects permitted the assignment of structural changes at positions 3, 7 and 12 of the steroidal nucleus.
