Front Cover: Recent Advances in the Catalytic Umpolung Carboxylation of Allylic Alcohol Derivatives with Carbon Dioxide (Asian J. Org. Chem. 5/2022)

Allylic alcohols and their derivatives are readily available organic compounds that frequently employed in synthesis. These allylic substrates add oxidatively to transition metals form π-allyl metal species, which instantly become nucleophilic under reductive conditions react with various electrophiles including the rather stable CO2 afford synthetically useful β,γ-unsaturated carboxylic acid derivatives. In this review, we focus on recent advances such catalytic umpolung carboxylations of allyl alcohols, acetates, pivalates, halides thermal, photochemical, electrochemical conditions.
