Some new compounds ( E)-3-aryl-1-(5-methyl-1- p-tolyl-1 H-1,2,3-triazol-4-yl)-prop-2-en-1-ones 5a-e were prepared by 1-(5-methyl-1- p-tolyl-1 H-1,2,3-triazol-4-yl)-ethanone and various aromatic aldehydes. Then one pot reaction was happened by compounds 5a-e with hydrazine hydrate in acetic acid or propionic acid, respectively, to give the title compounds 1acyl-5-aryl-3-(5-methyl-1- p-tolyl-1 H-1,2,3-triazol-4-yl)-4,5-dihydro-1 H-pyrazoles 6a-i. All structures were established by MS, IR, CHN, 1H-NMR and 13C-NMR spectral data. J. Heterocyclic Chem., (2012). [ABSTRACT FROM AUTHOR]

Some new target products 5-aryl-4,5-dihydro-3-(5-methyl-1- p-tolyl-1 H-1,2,3-triazol-4-yl)-1-(4-phenylthiazol-2-yl)pyrazoles 5a-j have been synthesized by reaction of 2-bromo-1-phenylethanone and compounds 4a-j which were prepared from the combination of thiosemicarbazide and ( E)-3-aryl-1-(5-methyl-1- p-tolyl-1 H-1,2,3-triazol-4-yl)-prop-2-en-1-ones 3a-j. All the structures were established by MS, IR, CHN, and 1H NMR spectra data. Synthesis of structure diversity is applied. J. Heterocyclic Chem., (2011). [ABSTRACT FROM AUTHOR]
