The illegal use of opiates and cocaine is a challenge world-wide, but some derivatives are also valuable pharmaceuticals. Reference samples of the active ingredients and their metabolites are needed both for controlling administration in the clinic and to detect drugs of abuse. Especially, 13C-labeled compounds are useful for identification and quantification purposes by mass spectroscopic techniques, potentially increasing accuracy by minimizing ion alteration/suppression effects. Thus, the synthesis of [acetyl-13C4]heroin, [acetyl-13C4-methyl-13C]heroin, [acetyl-13C2-methyl-13C]6-acetylmorphine, [N-methyl-13C-O-metyl-13C]codeine and phenyl-13C6-labeled derivatives of cocaine, benzoylecgonine, norcocaine and cocaethylene was undertaken to provide such reference materials. The synthetic work has focused on identifying 13C atom-efficient routes towards these derivatives. Therefore, the 13C-labeled opiates and cocaine derivatives were made from the corresponding natural products.
鸦片制剂和可卡因的非法使用是全世界面临的一个挑战,但其中一些衍生物也是很有价值的药物。无论是控制临床用药还是检测滥用药物,都需要活性成分及其代谢物的参考样本。尤其是 13C 标记的化合物,可用于质谱技术的鉴定和定量,通过最大限度地减少离子改变/抑制效应来提高准确性。因此,我们合成了[乙酰基-13C4]海洛因、[乙酰基-13C4-甲基-13C]海洛因、[乙酰基-13C2-甲基-13C]6-乙酰吗啡、[N-甲基-13C-O-甲酰-13C]可待因以及可卡因、苯甲酰可待因、去甲可卡因和古柯碱的苯基-13C6 标记衍生物,以提供此类参考材料。合成工作的重点是确定获得这些衍生物的 13C 原子高效路线。因此,13C 标记的鸦片制剂和可卡因衍生物是由相应的天然产品制成的。
