The present invention relates to a precursor of positron emission tomography (PET) radioactive medical supplies, a preparation method thereof, and an application thereof, and more specifically, to a precursor having a tetravalent organic salt leaving group, a preparation method, and a method for preparing desired PET radioactive medical supplies in a high radiochemical yield within a short preparation time by introducing
18
F using the same through a single step. The precursor having a tetravalent organic salt leaving group of the present invention can simplify the known complex multistep preparation of radioactive medical supplies into a single step, can save production costs because an excessive amount of a phase transfer catalyst is not required, facilitates separation of a compound after reaction, and enables rapid reaction velocity. The features are appropriate for the mass production of PET radioactive medical supplies by an automated synthesis system.
本发明涉及正电子发射断层扫描(PET)放射性医疗用品的前体、其制备方法及应用,更具体地,涉及一种具有四价有机盐离基的前体、其制备方法,以及通过引入
18
F并通过单步骤使用相同物质在短时间内高放射化学产率制备所需PET放射性医疗用品的方法。本发明的具有四价有机盐离基的前体可以将已知的复杂多步制备放射性医疗用品简化为单步骤,因为不需要过量的相转移催化剂,可以节省生产成本,促进反应后化合物的分离,并实现快速反应速度。这些特点适用于通过自动合成系统大规模生产PET放射性医疗用品。
