Asymmetric synthesis of arylglycines

Article abstract of DOI:10.1021/jo00299a009

The asymmetric synthesis of several arylglycines are reported. The methodology deployed involves either cuprate or Friedel - Crafts couplings to chiral bromoglycinates. The % ee's range from 82 to 94%. Both an oxidative and reductive protocol are employed to unmask the oxazinone chiral auxilliary providing the free α-amino acids.
