研究了三氟甲磺酸钪催化的芳胺或杂芳胺与[18F]表氟醇([18F]2)的N-[18F]氟烷基化反应。该反应是温和的,并提供了一步获得N-[18 F]氟烷基化芳基-或杂芳基-胺,这是用于正电子发射断层扫描成像。使用2,2,2-三氟乙醇作为助溶剂提高了反应效率。利用(S)-和(R)-[18 F] 2生成相应的对映体N-[18 F]氟烷基化苯胺。
The scandium triflate-catalyzedN-[18F]fluoroalkylation of aryl- or heteroaryl-amines with [18F]epifluorohydrin ([18F]2) was investigated. This reaction is mild and provides one-step access toN-[18F]fluoroalkylated aryl- or heteroaryl-amines, which are used for positron emission tomography imaging. The use of 2,2,2-trifluoroethanol as a cosolvent improved the reaction efficiency. The use of (S)- and (R)-[18F]2produced the corresponding enantiomericN-[18F]fluoroalkylated anilines.
