An efficient room temperature preparation of bromo difluorovinylzinc reagent (CF2CBrZnCl) and a high yield one-pot synthesis of α-bromo-β,β-difluorostyrenes
We have developed a new method for the synthesis of 2,3-dihydroquinazolin-4(1H)-ones in
good to excellent yields via phosphomolybdic acid (PMA)-catalyzed cyclocondensation of 2-
aminobenzamides with aldehydes or ketones in N,N-dimethylformamide (DMF) at room temperature.
The present method proves to be efficient in terms of short reaction time, high yield, simple workup
and easy purification.
An improved and rapid one pot synthesis of 2,4,6-triphenyl-1H-imidazoles on condensation with benzil, aromatic aldehyde and NH4OAc has been carried out using ZnO as an efficient and inexpensive catalyst in high yield at room temperature. The short reaction time, good yields (60-93%), environmental friendly procedure, mild reaction condition and convenient operation are important advantage of these synthetic methods.
AbstractStarting from readily available 2-naphthol, aldehydes, aryl and alkylamines, a variety of Betti bases were efficiently synthesized utilizing a catalytic amount of cerium (IV) ammonium nitrate (CAN) at room temperature. This protocol has advantages of high yield, mild reaction conditions, no environmental pollution, diversity of reactants and simple work up procedure.
A new and efficient one-pot synthesis of polysubstituted pyrrole derivatives by three-component reaction between dialkyl acetylenedicarboxylates, triphenylphosphine, 2-aminopyridin derivatives in the presence of arylglyoxals is described. The reactions were performed in dichloromethane at room temperature and neutral conditions and afforded high yields of products.
This paper presents a new method for fabricating biodegradable bio-polymeric nanoparticles via a convenient one-pot strategy at room temperature under stirring conditions for application to communicable diseases.
