A simple, direct synthesis route is provided for Ochratoxin compounds, particularly Ochratoxin A, Ochratoxin B, and Ochratoxin C. The reaction involves treating the dimethyl ester of 2-hydroxy-4-methylbenzene-1,3-dioic acid with a deprotonating agent, followed by addition of acetaldehyde, to provide a precursor compound, which can conveniently be converted to Ochratoxins A, B or C. The synthesis route allows for the first time laboratory and industrial scale synthesis of ochratoxins A, B and C in large quantities and pure form making them available as toxins, for use as anti-toxin investigation works, and for biological activity investigations and residue studies.
