This invention provides amino acid N-carboxyanhydrides, each of which has an N-acyl substituent on its nitrogen atom, is represented by the following formula (1):
readily reacts with nucleophilic reagents such as free amino acids, alcohols, anions or the like, and are intermediates useful for the high-yield production of amino acid derivatives, optically active compounds, peptides, polypeptides and the like useful in many fields lead by the fields of pharmaceuticals and agrochemicals, and also provides a process for the production of the amino acid N-carboxyanhydrides. Further, the present invention also provides a process for the production of diamides, which uses the compounds of the formula (1) and amine derivatives represented by the following formula (7):
These diamides can also be suitably used for the production of amino acid derivatives, optically active compounds, peptides, polypeptides and the like.
