  • Title: Asymmetric Synthesis of Allenyl α-Amino Amides by an Isothiourea Catalyzed Enantioselective [2,3]-Sigmatropic Rearrangement.
    Author: Zhang L, Zhang ZJ, Xiao JY, Song J.
    Journal: Org Lett; 2018 Sep 07; 20(17):5519-5522. PubMed ID: 30153032.
    Abstract:
    Highly efficient catalytic asymmetric [2,3]-sigmatropic rearrangements of propargyl ammonium salts have been accomplished under mild reaction conditions. In the presence of the chiral isothiourea catalyst, a wide range of allenyl α-amino amide derivatives were obtained in generally good yields (up to 99%) with excellent enantioselectivities (up to 96% ee).
