The synthesis of reference standards and expected in vivo metabolites of the first adenosine A3 PET radiotracer [18F]FE@SUPPY ([18F]fluoroethyl 4,6-diethyl-5-[(ethyl-sulfanyl)carbonyl]-2-phenylpyridine-3-carboxylate) was achieved by using a straightforward microwave assisted alkylation method, which allowed O/S-chemoselective alkylation of the starting material 1 to give each target compound 2–8 in a single step.
通过一种直接的微波辅助烷基化方法,成功合成了首个腺苷A3 PET放射性示踪剂[18F]FE@SUPPY([18F]氟乙基4,6-二乙基-5-[(乙基硫烷)羰基]-2-苯基吡啶-3-羧酸酯)的参考标准及其预期体内代谢物。该方法实现了起始物质1的O/S-化学选择性烷基化,使得每一目标化合物2-8均能在一部骤得到。
