Herein we suggest an approach to oxygenated bicyclic amino acids based on an aza‐Cope–Mannich rearrangement. Seven distinct amino acid scaffolds analogous to the natural products were prepared on a gram scale with precise control of stereochemistry. Successful implementation of our strategy resulted in the formalsynthesis of acetylaranotin.
