Journal ArticleDOI
The Chemistry of Pyrazolidinones. A Review
Rosa M. Claramunt,José Elguero +1 more
TL;DR: The CHEMISTRY of PYRAZOLIDINONES as mentioned in this paper has been described in detail in the Chemical Preparations and Procedures International: Vol. 23, No. 3, 1991, pp. 273-320.
Journal ArticleDOI
The structure of 2,3-dihydro-3-(2,4-dioxo-6-methylpyran-3-ylidene)- 2-(2-nitrobenzyl)-1,4-benzothiazine and the problem of orthogonal interactions
Elena Pinilla,María R. Torres,Rosa M. Claramunt,Dionisia Sanz,Richa Prakash,Shiv P. Singh,Ibon Alkorta,José Elguero +7 more
TL;DR: In this article, the structure of the title compound has been determined, which is consistent with previous conclusions based on NMR spectroscopy; moreover it provides new information about the conformation of the thiazine ring, the nature of the intramolecular hydrogen bond and the sulfur/nitro "orthogonal interaction".
Journal ArticleDOI
New N,C-Diaryl-1,2,4-triazol-3-ones: Synthesis and Evaluation as Anticancer Agents.
Dolores Santa María,Rosa M. Claramunt,José Elguero,Miguel Carda,Eva Falomir,Celia Martín-Beltrán +5 more
TL;DR: The synthesized 2,5-diaryl-1,2,4-triazol-3-ones showed relatively high activities together with very poor toxicity in non-tumor cell line HEK-293 and the downregulation of the synthetic triazolones on the expression of the hTERT, c-Myc and PD-L1 genes was measured by an RT-qPCR analysis.
Journal ArticleDOI
NMR studies of novel Schiff bases derived from L-α-amino methyl esters and 3-hydroxypyridin-4-carboxaldehyde
TL;DR: 2‐hydroxypyridin‐4‐carboxaldehyde and L‐α‐amino esters as well as those derived from the structurally related amines lacking the ester function have been synthesised.
Journal ArticleDOI
Azapentalenes. XLIV. 1H and 13C-NMR study of mesoionic pyrazolo[1,2-a]pyrazoles
TL;DR: The 1H and 13C chemical shifts as well as the 1H-1H and 1H−13C coupling constants of sixteen pyrazolo[1,2-a] pyrazole derivatives have been measured using resonance forms and simple additive models.
