carboxylic ortho esters could be used as an alkylating agent in the reductivealkylation of amines. A variety of amines, including amino acid esters, were alkylated affording mono‐alkylated products with high selectivity in practical to high yields using standard heterogeneous catalysts. By applying acyclic ortho esters alkylation was completed at room temperature.

A range of alpha-amino esters has been synthesized in good to high yields using a straightforward three-component reaction among preformed or in situ generated aromatic or benzylic organozinc reagents, primary or secondary amines, and ethyl glyoxylate. The procedure, which is characterized by its simplicity, allows the concise synthesis of esters bearing a phenylglycine or a phenylalanine scaffold.
