Diels-Alder derivatization for sensitive detection and characterization of conjugated linoleic acids using LC/ESI-MS/MS.

Tatsuya Higashi et al.

Analytical and bioanalytical chemistry, 403(2), 495-502 (2012-03-01)

The utility of Diels-Alder derivatization with 4-phenyl-1,2,4-triazoline-3,5-dione (PTAD) for liquid chromatography/electrospray ionization tandem mass spectrometry of conjugated linoleic acids (CLAs) was examined. PTAD rapidly reacted with the CLAs, and the resulting derivatives were highly responsive in electrospray ionization mass spectrometry

Oxa-ene reaction of enols of amides with 4-phenyl-1,2,4-triazoline-3,5-dione.

The Journal of organic chemistry, 73(1), 184-190 (2007-12-13)

The reaction of 16 enols of amides with 4-phenyl-1,2,4-triazoline-1,3-dione gave open chain adducts rather than the [2 + 2] cycloadducts with a hemiaminal moiety, both in solid state and in solution. This assignment is based on X-ray crystallography, (1)H and
