A novel multi-component reaction to imidazo[4,5-g]-quinazolines.
The trace impurities discovered after extended storage of a 5-amino- benzimidazole library were determined as imidazo[4,5-g]quinazoline derivatives by extensive spectroscopic data analysis. The formation of this highly aromatic heterocyclic ring involved a novel multi-component reaction, using which several novel compounds were prepared. Its mechanism was deduced as a cascade of chemical transf...
متن کاملA Novel Preparation of Zirconium Phosphate Nanoparticle and Its Application in Multi-Component Reactions
A novel method for the preparation of α-zirconium phosphate (ZrP) nanoparticles as an eco-friendly and recyclable heterogeneous catalyst was studied. Polyethylene glycol (PEG) was used as the organic matrix which produced a better dispersion of ZrP nanoparticles. The catalyst was characterized by several physicochemical...
متن کاملNovel defluorinative alkylation of trifluoroacetaldehyde N,O-acetal derivatives and its application to multi-component reaction.
The reaction of trifluoroacetaldehyde N,O-acetal derivatives with 2 molar equivalents of alkyllithium reagents proceeded viabeta-elimination of fluoride followed by alkyl transfer from excess alkyllithium to the generated ketene N,O-acetal intermediate at the beta-carbon of fluorine groups.
متن کاملA Novel Optimization Approach Applied to Multi-Pass Turning Process
Optimization of turning process is a non-linear optimization with constrains and it is difficult for the conventional optimization algorithms to solve this problem. The purpose of present study is to demonstrate the potential of Imperialist Competitive Algorithm (ICA) for optimization of multipass turning process. This algorithm is inspired by competition mechanism among imperialists and coloni...
