The Synthesis Of 3-Acetyl-5-Alkylpyridines

Autor: Frank C. Alderweireldt, E. L. Esmans

Publikováno v: Bulletin des Sociétés Chimiques Belges. 82:435-439

The synthesis of 3-acetyl-5-methyl- ; 3-acetyl-5-ethyl- ; 3-acetyl-5-propyl- and 3-acetyl-5-isopropylpyridine was accomplished by the condensation of the corresponding acroleine derivatives and 1-amino-1-buten-3-one.

Role of Nitrogen Lewis Basicity in Boronate Affinity Chromatography of Nucleosides

Autor: Bert U. W. Maes, Wouter A. Herrebout, Russell P. Newton, Edward G. Dudley, Robin Tuytten, E. L. Esmans, van der Veken Bj, Erwin Witters, Filip Lemière

Publikováno v: Analytical chemistry

Urinary modified nucleosides have a potential role as cancer biomarkers, and most of the methods used in their study have utilized low-pressure phenylboronate affinity chromatography materials for the purification of the cis-diol-containing nucleosid

Stainless steel electrospray probe: A dead end for phosphorylated organic compounds?

Autor: Robin Tuytten, W. Van Dongen, Erwin Witters, Russell P. Newton, Filip Lemière, Herman Slegers, E. L. Esmans, H. Van Onckelen

Publikováno v: Journal of chromatography: A

A study of the interaction of phosphorylated organic compounds with the stainless components of a liquid chromatography-electrospray ionisation-mass spectrometry system (LC-ESI-MS) was carried out to disclose a (forgotten?) likely pitfall in the LC-E

Short capillary ion-pair high-performance liquid chromatography coupled to electrospray (tandem) mass spectrometry for the simultaneous analysis of nucleoside mono-, di- and triphosphates

Autor: Robin Tuytten, E. L. Esmans, W. Van Dongen, Filip Lemière, Herman Slegers

Publikováno v: Rapid Communications in Mass Spectrometry. 16:1205-1215

A liquid chromatography/mass spectrometry (LC/MS) method for the analysis of complex mixtures of nucleoside mono-, di- and triphosphates has been developed. A short capillary column (35mm × 0.3mm i.d.) was operated under ion-pair high-performance li
