The direct catalytic enantioselective synthesis of protected aryl beta-hydroxy-alpha-amino acids.
The combination of three reagents-a tridentate pybox ligand (pybox = pyridine bis(oxazoline)), magnesium perchlorate, and Hünig base (iPr 2EtN)-allows the catalytic generation of a chiral glycine enolate from 1 that undergoes highly enantioselective addition to a range of aryl aldehydes 2. The prote...
