Asymmetric Hydroalkylation of Alkynes and Allenes with Imidazolidinone Derivatives: α-Alkenylation of α-Amino Acids

This work reports a new method for the synthesis of quaternary α-alkenyl substituted amino acids by the enantio- and diastereoselective addition of imidazolidinone derivatives to alkynes and allenes. Further hydrolysis...
