Novel (E)-ethyl 3-(dimethylamino)-2-(7,9-diphenyl-7H-pyrazolo[4,3-e][1,2,4]triazolo[1,5-c]pyrimidin-2-yl)acrylate (3A), was prepared via condensation of ethyl (1,3-diphenyl-1H-pyrazolo[4,3-e][1,2,4]triazolo[1,5-c]pyrimidin-5-yl)acetate (1) and dimeth...
A simple and novel route for the synthesis of new terphenyl derivative as well as oxidative aromatization of α,β-unsaturated cyclohexenone to the corresponding phenol derivative is developed. The present work involves the condensation of ethylacetoac...
1-(8-Chloro-3-methyl-1H-pyrazolo[4,3-c]cinnolin-1-yl)-2-(2-chlorophenyl)ethanone 2 has been synthesized through condensation of 3-acetyl-6-chloro-1H-cinnolin-4-one 1 with 2-(2-chlorophenyl)acetohydrazide in polar aprotic solvent containing catalytic...
A simple solvent-free synthesis of 3-[1-(4-methylphenyl)-3-oxo-1,3,4,5,6,7-hexahydro-2H-isoindol-2-yl]propanoic acid 3 was achieved by fusion of cis-2-[(4-methylphenyl)carbonyl]cyclohexanecarboxylic acid 1 with 3-aminopropanoic acid 2. The structure...
Novel ethyl (1,3-diphenyl-1H-pyrazolo[4,3-e][1,2,4]triazolo[1,5-c]pyrimidin-5-yl)acetate (5), was prepared via heating of 5-amino-1,3-diphenyl-4,5-dihydro-4-imino-1H-pyrazolo[3,4-d] pyrimidine (1) and diethyl malonate (2) under reflux. The structure...
The title compound, 2-(6-methoxynaphthalen-2-yl)propionic acid (1,3-dimethylbutylidene)hydrazide was synthesized in high yield by the reaction of 2-(6-methoxynaphthalen-2-yl)propionic acid hydrazide and 4-methylpentan-2-one in PEG 400. This compoun...
The title compound, N-(4-methylsulfonamido-3-phenoxyphenyl)-9,10-dihydro-9,10-ethanoanthracene-11,12-dicarboximide was synthesized in high yield by reaction of N-(4-amino-2-phenoxyphenyl)methanesulfonamide and 9,10-dihydroanthracene-9,10-endo-α,β-suc...
4-Amino-N-(2-hydroxy-4-pentadecylbenzylidene)benzenesulfonamide has been synthesized by reaction of 2-hydroxy-4-pentadecylbenzaldehyde with 4-aminobenzenesulfonamide in the presence of acetic acid in ethanol. The structure of this new compound was co...
