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.
本文提供了一种简单、直接的合成途径,用于制备Ochratoxin化合物,特别是Ochratoxin A、Ochratoxin B和Ochratoxin C。反应涉及将2-羟基-4-甲基苯-1,3-二酸二甲酯与去质子剂处理,随后加入乙醛,提供一个前体化合物,可以方便地转化为Ochratoxins A、B或C。这种合成路线首次允许在实验室和工业规模上大量、纯形式地合成ochratoxins A、B和C,使它们可作为毒素,用于抗毒素研究工作,以及生物活性研究和残留物研究。
