title: Pyrazolo[1,5-a]pyrimidines. A combined multinuclear magnetic resonance (1H, 13C, 15N, 19F) and DFT approach to their structural assignment.
abstract: Multinuclear magnetic resonance spectroscopy together with GIAO-DFT calculations allowed establishment of the structure of the products obtained by condensation of 3(5)-amino-4-phenyl-1H-pyrazole and beta-dicarbonyl compounds bearing a trifluoromethyl group. They are 3-phenyl-5-(R)-7-trifluoromethylpyrazolo[1,5-a]pyrimidines.
