Oxidation-assisted structural elucidation of compounds containing a tertiary amine side chain using liquid chromatography mass spectrometry
A novel analytical technique for the structural elucidation of compounds bearing a tertiary amine side chain via “in vial” instantaneous oxidation and liquid chromatography mass spectrometry (LC-MS) was developed. A series of lidocaine homologs and benzimidazole derivatives with a major/single amine representative base peak in both their EI-MS and ESI-MS/MS spectra were subjected to oxidation by a 0.1% solution of hydrogen peroxide (including several 16O/18O exchange experiments), followed by LC-ESI-MS/MS analysis. The N-oxide counterparts promoted extensive fragmentation with complete coverage of all parts of the molecule, enabling detailed structural elucidation and unambiguous identification of the unoxidized analytes at low nanogram per milliliter levels.

Selectivities in the oxidation of tertiary amines and pyridine derivatives by perfluoro cis-2,3-dialkyloxaziridines
When tertiary amines 1 are reacted with perfluoro cis-2,3- dialkyloxaziridines 2 at -60 °C corresponding N-oxides 3 are formed in high yields. The process is chemoselective and diastereoselective. The chemoselectivity in the reaction of alkenyl substituted pyridines is solvent dependent, attack occurring exclusively at the carbon-carbon double bond or at the nitrogen atom under protic and aprotic conditions, respectively. Lower selectivities were obtained when standard reagents were used.
