Methods for the preparation of 1-Aminocyclopropanecarboxylic Acids

Resumo

The derivatives of 1-aminocyclopropanecarboxylic acid (ACC) over recent decades have attracted close attention from synthetic chemists owing to their high physiological activity as plant growth regulators, conformationally rigid analogs of natural amino acids, and peptidomimetics. The present review considers contemporary approaches to the methods of preparation of amino acids of the ACC series, namely, the alkylation of glycine equivalents with 1,2-electrophiles, the intramolecular cyclization of γ-substituted amino acid derivatives, alkene cyclopropanation under the action of diazo compounds, ylides, and carbene intermediates, as well as other synthetic approaches.
