A solid supported glycineimine t-butyl ester was designed and successfully applied to the synthesis of (divided by)-alpha-amino acids. The phase-transfer catalytic alkylation, followed by acidic hydrolysis and benzoylation gave N-benzoyl-alpha-amino acid tert-butyl esters in high yields (up to 92%). (C) 2004 Elsevier Ltd.
