The diastereoselective synthesis of α-amino esters from the glycine ester (I) employing the sulfonamides (II) as chiral auxiliaries works well for α-alkylation with methyl iodide. Ethylation, allylation, and benzylation proceeds with fair stereoselectivity, but pure diastereomers can be obtained by
