The enantioselective electrochemical lactonization of diketo acid derivatives using
chiral iodoarenes as redox mediators is reported for the first time. Good to high
stereoselectivities are observed in the lactonization and also in intermolecular α-alkoxylations
of diketo ester derivatives. This enantioselective process was then adapted to an
electrochemical flow microreactor where only small amounts of supporting electrolyte
were necessary.
