Bicatalyzed Three-Component Stereoselective Decarboxylative Fluoro-Aldolization for the Construction of Elongated Fluorohydrins

A bicatalyzed three-component cascade between simple aliphatic enolizable aldehydes, a fluorine source, and keto acids has allowed the diastereoselective and enantioselective direct synthesis of carbonyl-elongated vicinal fluorohydrins. The obtained complex acyclic functionalized molecules, possessing up to four stereogenic centers controlled in usually >95% ee, hold great promise for further synthetic developments and rapid incorporation in bioactive elaborated structures
