Organocatalytic Synthesis of α,α–Diaryl Substituted α–Amino Acid Derivatives by an Interrupted Three-Component Ugi Reaction

An organocatalytic interrupted three-component Ugi reaction for the synthesis of α, α–diaryl α– amino acid derivatives is described. The transformation proceeds with a range of isocyanides and 3-aryl isoindolinone alcohols using Brønsted acid catalysts to afford products in good to excellent yields. Based on the obtained results, a reaction mechanism is proposed and discussed.
