which are generally employed in PET tracer synthesis. Therefore, we set out to develop a general procedure for the synthesis of para-11CH3 labeled aromatic amines from the corresponding para-aminoarylboronic esters in the presence of free amines. Aryl boronic esters containing primary, secondary, and tertiary amines were successfully converted into corresponding labeled methyl derivatives in sufficient
交叉偶联是PET示踪剂合成中通常使用的常规11 C-甲基化的替代方法。因此,我们着手开发的一般过程用于合成对位- 11 CH 3个从对应的标记的芳香族胺段中的游离胺的存在-aminoarylboronic酯。含有伯,仲和叔胺的芳基硼酸酯已成功地以足够的放射化学收率转化为相应的标记甲基衍生物,以将该方法用于示踪剂开发。此程序已应用于CIMBI-712的标签,CIMBI-712是中枢神经系统中5-HT 7受体体内成像的有希望的候选者。
