catalytic arylhydroxylation of dehydroalanine with aryldiazonium salts. Aryldiazonium salts, which are generated from aniline precursors under partially aqueous conditions in continuous flow, efficiently reacted with dehydroalanine in the presence of 10–15 mol % ferrocene to furnish α‐hydroxyarylalanine derivatives (up to 82 % yield). The reactions proceeded with regioselectivity, broad functional
