A simple method for the synthesis of a pyrazolyl thiazole derivative containing a piperonal moiety was developed. Thus, 2-{5-(1,3-benzodioxol-5-yl)-1-[4-(4-chlorophenyl)-1,3-thiazol-2-yl]-4,5-dihydro-1H-pyrazol-3-yl}pyrazine was synthesized using mic...

The title compound, 5-[(3,5-dimethyl-1-phenyl-1H-pyrazol-4-yl)methylene]-1,3-diethyl-2-thioxodihydropyrimidine-4,6(1H,5H)-dione, has been synthesized by condensation of 1,3-diethyl-2-thiobarbituric acid and 3,5-dimethyl-1-phenylpyrazole-4-carbaldehyd...

A novel compound, 5,5'-(1,4-phenylenedimethylylidene)bis(1,3-diethyl-2-thioxodihydropyrimidine-4,6(1H,5H)-dione) (3) has been synthesized by condensation of 1,3-diethyl-2-thiobarbituric acid and terephthalaldehyde in anhydrous ethanol in the presence...

A new compound, 1,3,5-tris-(2,3-dihydro-1H-1,5-benzodiazepin-4-yl)-1,2,3,4,5,6-hexahydro-s-triazine was obtained by the reaction of ortho-phenylenediamine 1 with 1,3,5-triacryl-1,2,3,4,5,6-hexahydro-1,3,5-triazine 2. Spectroscopic (IR, 1H-NMR, 13C-NM...

The title compound, 1-{[(3,4-dimethylisoxazol-5-yl)imino]methyl}-2-naphthol has been synthesized by condensation of 5-amino-3,4-dimethylisoxazole and 2-hydroxy-1-naphthaledhyde in ethanol. The structure of this new compound was confirmed by elemental...

Lariat ethers are interesting recognition motifs in supramolecular chemistry. The synthesis of a luminescent lariat aza-crown ether with a carboxyl group appended by azide-alkyne (Huisgen) cycloaddition is presented.

Lariat ethers are interesting recognition motifs in supramolecular chemistry. The synthesis of a luminescent lariat ether with triglycol chain by azide–alkyne (Huisgen) cycloaddition is presented.

The title compound was prepared by treatment of 1-(2-chlorophenyl)-3-methyl-2-pyrazolin-5-one with 2-chlorobenzoyl chloride / Ca(OH)2 in 1,4-dioxane and subsequent cyclization of the thus obtained 4-aroyl-5-hydroxypyrazole with sodium hydride in dry...

A luminescent aza-27-crown-9 ether amino acid was prepared by a three-step reaction sequence. The compound signals ammonium ion binding by an increase in emission intensity.

The title compound, N-[1-(2,5-dimethyl-3-thienyl)ethylidene]-1,3-benzothiazol-2-amine has been synthesized by condensation of 2-aminobenzothiazole and 3-acetyl-2,5-dimethylthiophene in ethanol. The structure of this new compound was confirmed by elem...
