✦ Synopsis

13C N M R chemical shift assignments for 30 trans -alkoxy-8-methyl -Bn itrostyrenes and the parent compound were measured and interpreted. Chemical shift assignments for 2 0 of these compounds have not been reported previously. Data are based on a number of 1D and 20 experiments performed at 9.4 T.

## Abstract 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
