Synthesis and ESI-MS/MS fragmentation study of two new isomeric oxazolidin-2-one derivatives

Two new isomeric oxazolidin-2-one derivatives have been synthesized through reaction of (E)-3-styrylquinoxalin-2-one with bis-dichloroethylamine hydrochloride in presence of potassium carbonate. The structures of the formed products were established by NMR and mass spectroscopy. The fragmentation patterns of the two novel synthesized oxazolidin-2-ones (1, 2), possessing the same backbone structure, were investigated using electrospray ionization mass spectrometry (ESI-MS) and tandem mass spectrometry (MS/MS) techniques. A simple methodology, based on the use of ESI (positive ion mode) and by increasing the declustering potential in the atmospheric pressure/vacuum interface, collision induced dissociation (CID), was used to enhance the formation of the fragment ions. In general, the novel synthetic oxazolidin-2-one derivatives afforded, in the gas phase, protonated molecules leading to the confirmation of the molecular masses and chemical structures of the studied compounds. The breakdown routes of the protonated molecules were rationalized by conducting low-energy collision CID-MS/MS analyses (product ion scans) using. The structural similarity between the two studied oxazolidin-2-ones explains the similarity observed in their CID-MS/MS spectra and their fragmentation pathways. ESI-MS/MS recorded with increased collision energy values permits us to observe different product ions and allow us to differentiate the two studied isomers. ESI-MS and CID-MS/MS analyses have thus proven to be a specific and very sensitive method for the structural investigation of the two novel synthesized oxazolidin-2-one derivatives.

Role of aqueous methyldiethanolamine (MDEA) as solvent in natural gas sweetening unit and process contaminants with probable reaction pathway

Aqueous methyldiethanolamine (MDEA) is used as a solvent in natural gas sweetening unit, whose quality deteriorates while absorbing H2S/CO2 causing corrosion and foaming in the process. Total process contaminants of lean MDEA obtained from GASCO Company (Habshan, Abu Dhabi) were determined using different instruments. The major hydrocarbons found in inlet natural gas was analyzed using gas chromatography mass spectrometry (GC-MS). Heat stable salt (HSS) anions and metal ions were detected using ion chromatograph (IC) and inductively coupled plasma optical emission spectrometry (ICP-OES). Liquid chromatography mass spectrometry (LC-MS) and direct sample analysis time of flight (AxION 2TOF) analysis were carried out to determine and major organic degraded products present in lean MDEA solvent. The UV-VIS spectrophotometer also justified the presence of total organic acid anions. Acetate and propionate were found to be present in higher amounts of 2806 and 1614 ppm, respectively. Substantial amount of metal ions were also detected using ICP-OES with maximum level of heavy metal ions of lead and iron of 1.009 and 0.967 ppm, respectively. Large numbers of organic degraded products such as diethanolamine followed by methylethanolamine, N,N-bis(2-hydroxyethyl) glycine (bicine) etc. were identified using LC-MS and AxION 2TOF analyses; which are considered to be major organic thermally degraded products. Thermal degradation experiment was compared with H2S and in presence of both H2S/CO2 to obtain same compounds with varying concentration. On the basis of MDEA degradation as reported by previous researchers and from the analyzed lean MDEA samples, probable reaction pathways have been proposed.

On the structure of the Phytophthora alpha1 mating hormone: synthesis and comparison of four candidate stereoisomers

Two two-compound mixtures of candidate structures for the Phytophthora alpha1 mating hormone have been synthesized. The mixtures were designed to have differing configurations at C3, but proved to be identical. This suggests that epimerization occurred at C3, and comparison with the data for the natural samples suggest that this is also a mixture of isomers.
