RISA new leaving group in nucleophilic aromatic substitution reactions - Sn Ar
A new leaving group in nucleophilic aromatic substitution reactions - Sn Ar
Ferric hydrogensulfate as a recyclable catalyst for the synthesis of some new bis(indolyl)methane derivatives
New bis(indolyl)methanes were synthesised in excellent yields by the reaction of indole derivatives with aromatic
and aliphatic aldehydes in the presence of ferric hydrogensulfate as an efficient, inexpensive, ...
Glycoluril-derived crown clips as new ditopic receptors
Several new ditopic receptors have been synthesized from 4,4\\'-bis(methoxyphenyl)glycoluril (1). The first receptor site is a cleft composed of two fused 2-imidazolone rings, which are flanked by two aromatic side walls, ...
An efficient synthesis of imidazo[4,5-a]acridine-11-yl cyanides as new fluorescent heterocylic compounds
One of the most general mechanisms to transforming of δH-adducts into products of nucleophilic substitution of hydrogen is conversion of δH-adducts into nitroso compounds under proper conditions. This conversion occurs ...
TiO2 nanoparticles: an efficient heterogeneous catalystfor synthesis of bis(indolyl)methanes under solvent-free conditions
Some bis(indolyl)methanes have been synthesized,
in excellent yields, under solvent free conditions, by
reaction of indoles with aromatic and aliphatic aldehydes in
the presence of nano titanium(IV) ...
Synthesis and antibacterial activity of some new derivatives of pyrazole
In this study, we report the synthesis and
antibacterial activity of a new series of 5-amido-1-(2,4-
dinitrophenyl)-1H-4-pyrazolecarbonitriles. Our results
show that all compounds exhibit antimicrobial ...
The synthesis of highly fluorescent heterocyclic compounds: Pyrido[2,1:2,3]imidazo[4,5-b]quinoline-12-yl cyanides
The syntheses and fluorescence properties of novel derivatives of pyrido[20,10:2,3]imidazo[4,5-b]quinoline
are described. The key intermediates (4-substituted)(3-hydroxyimino-2,3-dihydroimidazo[1,2-a]
pyrid ...
An Efficient One-Pot Synthesis of a New Heterocyclic System with High-Fluorescent Properties
Nucleophilic substitution of hydrogen in nitro derivative of imidazo[1,2-a]pyridine has been used as a key
step in the one-pot synthesis of a new highly fluorescent heterocyclic system pyrido
[100,200:10,20 ...
SULFURIC ACID MEDIATED HETEROCYCLIZATION OF ORTHO- CYANOMETHYLNITROARENES TO BENZO[C]ISOXAZOLES AND FUSED BENZO[C]ISOXAZOLES
SULFURIC ACID MEDIATED HETEROCYCLIZATION OF ORTHO- CYANOMETHYLNITROARENES TO BENZO[C]ISOXAZOLES AND FUSED BENZO[C]ISOXAZOLES
Synthesis of a new heterocyclic system Fluoreno[1,2-d]imidazol-10-one
Fluorenones (fluorine-9-ones) are among the oldest classes of bioactive compounds,
which are widely used as antiviral [1] and anticancer agents and act as the key synthetic
intermediates in many reactions. ...
