Syntheses and antiinflammatory activity of some 6-aryl-2,3,4,5-tetrahydro-3-pyridazinones
Khan,Siddiqui
, p. 614 - 619 (2007/10/03)
6-Aryl-2, 3, 4, 5-tetrahydro-3-pyridazinones (2c-22c) are obtained by dehydrocyclisation of various hydrazides formed by the reaction of appropriate methyl β-aroylpropionate and hydrazine hydrate in the presence of anhydrous sodium acetate. They show promising antiinflammatory activity during their evaluation by carrageenin induced paw edema test in rats.
ALKYLATION OF 6-OXO-1,6-DIHYDROPYRIDAZINES BY TRIETHYLOXONIUM FLUOROBORATE
Volynets, N. F.,Smartseva, I. V.,Khramova, I. V.,Pavlova, L. A.
, p. 1604 - 1608 (2007/10/02)
Irrespective of the nature of the substituents at positions 1 and 3 the heterocycle, 6-oxo-1-phenyl(methyl)-3-aryl-1,6-dihydropyridazines are alkylated by the action of triethyloxonium fluoroborate at the oxygen atom of the carbonyl group, forming heteroaromatic 1-ethoxypyridazinium salts.
