Efficient enantioselective synthetic methods for (R)-α- alkylhomoserines and (R)-α-alkylhomocysteines have been developed. The phase-transfer catalytic alkylation of 2-phenyl-5,6-dihydro-4H-1,3-oxazine-4- carboxylic acid tert-butyl ester and 2-phenyl-5,6-

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