Synthesis of 4-amino-1,5-dimethyl-2-phenylpyrazolone derivatives and their antioxidant activity

Schiff bases of 4-amino-1,5-dimethyl-2-phenylpyrazolone (2-18) were synthesized by treating with different benzaldehyde derivatives and tested for in vitro antioxidant activity. Synthesized Schiff base derivatives (2-18) were characterized by various spec

Molecular structure of di-aryl-aldimines by multinuclear magnetic resonance and X-ray diffraction

The complete 1H, 13C and 15N NMR analyses for a series of 25 diaryl-aldimines containing phenyl, pyridyl, pyrazolone and furanyl moieties are described herein. Detailed evaluation of substituent chemical shift and coupling constant effects showed that interaction between the lone pair of the pyrazolone carbonyl group or the nitrogen of 2-substitued pyridines with the aldimine hydrogen increases the 1JCH value and shifts the resonance signal for this hydrogen to high frequency, in the 1H NMR spectra. The X-ray crystal structure analysis of pyrazolone substituted aldimines evidenced the planarity of the aryl groups which are conjugated with the C=N double bond. In the case of the N-(2-pyridinemethylene)-1,5-dimethyl-2-phenyl-1,2-dihydro-pyrazol-3-one, two rotamers were observed in the same unit cell.

Microwave-mediated synthesis of amines from heterocyclic amines and aldehydes

Imines derived from heterocyclic amines and aldehydes can be readily prepared, in a domestic microwave oven, by reaction on a basic solid support and in the absence of solvent.
