## Abstract A re‐analysis of previously published ^13^C NMR data on C‐7‐substituted 6α,14α‐__endo__‐ethanotetrahydrothebaines shows that the ^13^C chemical shift of C‐18 in these medicinally important compounds can be used as an indicator of C‐7 stereochemistry, this being due to a steric gamma eff
