The reduction of normal‐, allo‐, epiallo‐, and pseudo‐berbanones were studied under different conditions. Reduction with Na/alcohol always led to the thermodynamically controlled products while catalytic and NaBH4 reduction resulted almost exclusively in the kinetically controlled compounds. An interesting correlation was observed between the MS fragmentation and ring C/D stereochemistry.
