During the development of a new route to AZD2563 DSP (DSP = disodium phosphate), a selective enzyme-catalysed hydrolysis of a 1,2-diester moiety to produce the secondary monoester was developed. Apart from two esters, the target molecule also contained three further functional groups prone to hydrolysis. A major challenge to the chosen approach was the very facile rearrangement of the desired secondary
在开发通往AZD2563 DSP的新路线(DSP =磷酸二钠)的过程中,开发了一种选择性酶催化的1,2-二酯部分水解以生产仲单酯的方法。除了两种酯以外,目标分子还包含三个易于水解的其他官能团。所选方法的主要挑战是将所需的二级单酯产物非常容易地重排为不希望的一级单酯。发现这种重排是由通常被认为是惰性的多种化学物质和无机材料催化的。生物催化的独特选择性和温和的操作条件使所需的反应得以开发并成功扩大规模。
