The 13 C NMR spectra were recorded and assigned for nine derivatives of methyl 5β‐cholan‐24‐oates (esters of bile acids) including hydroxy, oxo and/or acetyloxy groups. Assignments were based on the empirical substituent‐induced chemical shifts (SCS), spectral comparison with compounds of similar structure, distortionless enhancement by polarization transfer (DEPT) and proton coupled 13 C NMR measurements.
