Synthesis of Substituted Furans from β‐Ketoanilides Using Ethylene Glycol as C2‐Precursor

Abstract A transition‐metal‐free oxidative method to synthesize substituted furans from β‐ketoanilides and vicinal diols was reported. This approach accommodates a wide range of functional groups (e. g., halogens, methoxy, methyl, nitro) and enables the regioselective formation of 2,3‐disubstituted and 2,3,5‐trisubstituted furans via base‐promoted oxidative C−C and C−O bond formation. Additionally, substituted pyrroles were synthesized regioselectively from β‐ketoenamines using ethylene glycol as a C 2 precursor.
