N-Carbobenzoxy-alpha-alkoxyglycine esters were synthesized by H2SO4-catalyzed O-alkylation of N-carbobenzoxy-alpha-hydroxyglycine and also by base treatment of N-carbobenzoxy-N-chloroglycine methyl ester in the corresponding alcohol. Saponification of the protected alpha-alkoxyglycines gave free acids which can be used for the synthesis of alpha-alkoxyglycine residue-containing peptides.
