B. Matuszczak et al., ACYLATION OF A NOVEL QUINOXALINYL SUBSTITUTED PYRAZOLE DERIVATIVE - SYNTHESIS, QUANTUM-CHEMISTRY CALCULATIONS, AND X-RAY STRUCTURE-ANALYSIS, Journal of heterocyclic chemistry, 35(1), 1998, pp. 113-115
The preparation of N-acetylpyrazolyl-quinoxalines and results of semie
mpirical MO calculations are presented. The structure determination of
the isomers 3a,b was achieved by X-ray analysis.
