the Ugi four-center three-componentreaction (U4C-3CR). For the first time, γ-aminobutyric acid is employed as bifunctional input in the Ugireaction. This protocol is simple, general, and allows one-pot access to a range of drugs and bioactive small molecules. We report the synthesis of racetams, a diverse class of small molecule drugs, by means of the Ugi four-center three-componentreaction (U4C-3CR)
