A new spiro[indole-3,3'-pyrrolizine] derivative is regioselectively synthesized by the straightforward multicomponent reaction of 1-(4-fluorophenyl)-3-phenylprop-2-en-1-one, isatin and L-proline without any catalyst. The structure of the newly synthe...
In this paper (R)-7-(azepan-3-ylamino)-8-chloro-1-cyclopropyl-6-fluoro-4-oxo-1,4-dihydroquinoline-3-carboxylic acid hydrochloride 1 was isolated and identified as the N-substituted regioisomer of besifloxacin, which has been synthesized from the reac...
S-Alkylation of 5-(diphenylmethyl)-1,3,4-oxadiazole-2(3H)-thione (3) by 2-chloro-N-(pyrazin-2-yl)acetamide (2) affords the title compound, 2-{[5-(diphenylmethyl)-1,3,4-oxadiazol-2-yl]sulfanyl}-N-(pyrazin-2-yl)acetamide (4). The intermediate (2), in t...
3,3'-(1,4-Phenylenebis(phenylazanediyl))bis(7-ethoxy-4-methyl-2H-chromen-2-one) was synthesized from N,N'-diphenylbenzene-1,4-diamine and bromo-7-ethoxy-4-methylcoumarin based on Ullmann coupling reaction. The synthesized compound was characterized b...
A novel synthetic methodology for preparation of thiocarbohydrazone by reacting thiocarbohydrazide with 1-acetyl-5-chloroisatin is described. The title compound was prepared by condensation of thiocarbohydrazide and substituted isatin in aqueous etha...
The title compound, 2-chloro-7-methyl-3-({4-[(4-nitrophenoxy)methyl]-1H-1,2,3-triazol-1-yl}methyl)quinoline was synthesized in one pot. The structure of the compound was fully characterized by IR, 1H and 13C-NMR, mass spectral analysis and elemental...
