Synthesis of phenyl-13C6-ethene

In an effort to prepare an improved carbon-rich target material for the accelerator production of 13N labelled ammonia for use in positron emission tomography (PET), sulfonated poly(styrene/divinylbenzene) has been evaluated. The preparation of this target material using naturally abundant carbon-12 compounds was investigated in an effort to optimize conditions for the preparation of the analogous carbon-13 target material which may provide a cost-effective method for producing nitrogen-13 labelled ammonia via proton irradiation. As part of this study, phenyl-13C6-ethene was synthesized in three steps starting from benzene-13C6.

A stable isotope labeled 2 - isopropyl thioxanthone and its synthesis method

The invention relates to stable isotopic labeled 2-isopropylthioxanthone and a synthetic method thereof. The stable isotopic labeled 2-isopropylthioxanthone is 2-isopropylthioxanthone labeled by D or 13C. The synthetic method comprises the following steps of using benzene and acetone which are labeled by stable isotopic D or 13C as raw materials; reacting the benzene and the acetone with magnesium to obtain Grignard reagent after benzene bromination; performing reduction and hydroxide radical bromination on the acetone to obtain 2-bromic propane; performing Grignard reaction to obtain isopropyl benzene; reacting the isopropyl benzene with dithio-salicylic acid; and synthesizing to obtain the 2-isopropylthioxanthone labeled by the stable isotopic D or 13C. Compared with the prior art, the stable isotopic labeled 2-isopropylthioxanthone has the advantages that a process route is simple, the 2-isopropylthioxanthone is easy to synthesize, products are easy to separate and purify, the chemical purity of the products is above 99.0%, isotope abundance is above 98.0% atom, requirements of trace detection in the field of food safety can be met fully, and economical efficiency and using value are excellent.

Synthesis of [13C6]-labelled phenethylamine derivatives for drug quantification in biological samples

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.
