development of a catalytic antibody for the hydrolysis of the lactone functionality in zearalenone (1) is viewed as a potential solution to animal fertility problems associated with the estrogenic mycotoxin. A phosphonomacrolactone is proposed as a hapten for the generation of such antibodies. A suitably functionalized aryl phosphonic acid 4 was condensed with the racemic aliphatic fragment 5 via a Mitsunobu
用于玉米赤霉烯酮(1)中内酯官能团水解的催化抗体的开发被认为是解决与雌激素性霉菌毒素相关的动物繁殖力问题的潜在解决方案。提出了磷酰基大环内酯作为用于产生这种抗体的半抗原。经由Mitsunobu反应将适当官能化的芳基膦酸4与外消旋脂族片段5缩合。通过RCM实现大环形成,得到高级中间体23,玉米赤霉烯酮的膦酸酯类似物,准备去保护并缀合到载体蛋白上。
