The availability of high-quality 13C-labelled internal standards will improve accurate quantification of narcotics and drugs in biological samples. Thus, the synthesis of 10 [13C6]-labelled phenethylamine derivatives, namely amphetamine, methamphetamine, 3,4-methylenedioxyamphetamine, 3,4-methylenedioxymethamphetamine, 3,4-methylenedioxy-N-ethylamphetamine, 4-methoxyamphetamine, 4-methoxymethamphetamine, 3,5-dimethoxyphenethylamine 4-bromo-2,5-dimethoxyphenethylamine and 2,5-dimethoxy-4-iodophenethylamine, have been undertaken. [13C6]-Phenol proved to be an excellent starting material for making 13C-labelled narcotic substances in the phenethylamine class, and a developed Stille-type coupling enabled an efficient synthesis of the 3,4-methylenedioxy and 4-methoxy derivatives. The pros and cons of alternative routes and transformations are also discussed. The [13C6]-labelled compounds are intended for use as internal standards in forensic analysis, health sciences and metabolomics studies by gas chromatography-mass spectrometry and liquid chromatography-tandem mass spectrometry.

高质量的13C标记内标的可用性将提高生物样本中麻醉剂和药物的精确定量。因此,合成了10种[13C6]标记的苯乙胺衍生物,即安非他命、甲基安非他命、3,4-亚甲基二氧安非他命、3,4-亚甲基二氧甲基安非他命、3,4-亚甲基二氧-N-乙基安非他命、4-甲氧基安非他命、4-甲氧基甲基安非他命、3,5-二甲氧基苯乙胺、4-溴-2,5-二甲氧基苯乙胺和2,5-二甲氧基-4-碘苯乙胺。 [13C6]-苯酚被证明是制造苯乙胺类13C标记麻醉剂的优良起始材料,发展起来的Stille型偶联促进了3,4-亚甲基二氧和4-甲氧基衍生物的高效合成。同时讨论了替代路线和转化的利弊。这些[13C6]标记化合物旨在作为法医分析、健康科学和代谢组学研究中气相色谱-质谱和液相色谱-串联质谱的内标使用。版权 © 2014 John Wiley & Sons, Ltd.
