The invention provides a process for preparing amino acid esters and/or their acid addition salts from monomeric or polymeric amino acids, peptides, proteins and alcohols, which comprises carrying out the reaction in supercritical alcohols, preferably at pressures and temperatures which are at least 5% above the critical parameters, the alcohols serving both as the solvent and as reactants.

The titled triazine can be alkylated with LDA and a variety of alkyl halides: Subsequent reduction with aluminium amalgam cleaves the naphthotriazine moiety to afford substituted α amino acids in excellent overall yields; the sequence defines a novel methodology that can be applied under non-acidic and largely non-aqueous conditions.
