## Abstract The configurational assignment of stereoisomeric 3‐bromo‐3‐acyl derivatives of steroids in both the 5α and 5β series has been carried out by comparing the ^13^C chemical shifts of C‐3. A downfield shift is observed for C‐3, bearing a bromine and an acyl group, on going from the isomer w
