In the present article we show that, although reflux method is not common for synthesis of multicomponent MoVTeNbO catalysts, an optimized metallic precursors leads to...

Substituted imidazoles are of interest because their useful biological activities. While several methods have been developed for the synthesis such compounds, some reported utilize corrosive or toxic catalysts. We report a bismuth (III) triflate catalyzed multicomponent 2,4,5-trisubstituted imidazoles. Bismuth compounds attractive from green chemistry perspective they remarkably non-toxic and n...

1,5-benzodiazepines are regarded as one of the most important classes of heterocyclic compounds as privileged structures and have vast range of applications in the field of medicine and chemistry. They are therefore attractive synthetic targets for organic and medicinal chemist. The current review article mainly covers the multicomponent green chemistry approaches for the synthesis of 1,5-benzo...

the development of multicomponent reactions (mcrs) designed to produce elaborate biologically active compounds has become an important area of research in organic, combinatorial, and medicinal chemistry. a comparative study of the synthesis of new bis-spiro-oxindolo(pyrrolizidines/pyrrolidines) ring systems by the cycloaddition of azomethine ylides generated by a decarboxylative route from sarc...

A novel multicomponent synthesis of ketene dithioacetal rhodanines has been reported by reactions of primary amine, carbon disulfide, ethyl chloroacetate, and alkyl halide in DMF. The catalytic effects of different bases have been investigated and potassium carbonate can efficiently catalyze the reaction in moderate to good yields at room temperature. 2013 Elsevier Ltd.
