Controllable Regioselective Construction of Both Functional α-Methylene-β- and -γ-amino Acid Derivatives Through an Organocatalyzed Tandem Allylic Alkylation and Amination
A new controllable and regioselectiveallylicalkylation and amination reaction has been developed for the highly selective construction of compounds containing α-alkylidene-β-amino acid and α-methylene-γ-butyrolactam moieties. Furthermore, on the basis of this controllable strategy, multicomponent tandem reactions have also been accomplished. The subsequent transformations of the densely functionalized
