Mechanistic details for each step in the DFRC process. Acetylation of hydroxyl units and bromination of benzylic positions by acetyl bromide (AcBr)/acetic acid (AcOH) (derivatization) precede two‐electron reductive cleavage of β‐ethers and debromination of cinnamate‐derived moieties via zinc/acetic acid. In the final step the product mixture is acetylated using a mixture of acetic anhydride (Ac2O)/pyridine.
