A simple and convenient synthesis of [1,2,4]triazolo/benzimidazolo quinazolinone and [1,2,4]triazolo[1,5-a]pyrimidine derivatives catalyzed by DABCO-based ionic liquids

DABCO-based ionic liquids were utilized for the preparation of [1,2,4]triazolo/benzimidazolo quinazolinone and [1,2,4]triazolo[1,5-a]pyrimidine derivatives in the adequate procedures. These methods involve three-component reaction between aldehydes, β-dik

Preparation and characterization of a novel DABCO-based ionic liquid supported on Fe3O4@TiO2 nanoparticles and investigation of its catalytic activity in the synthesis of quinazolinones

In this study, quinazolinone derivatives have been synthesized via a suitable and efficient procedure by one-potmulti-component reactions of 3-amino-1,2,4-triazole or 2-aminobenzimidazole, dimedone and aromatic aldehydes in the presence of Fe3O

Nanostructured γ-Fe2O3@starch-n-butyl SO3H as new recyclable magnetic catalyst for promoting multi-component reactions

Butane-1-soltunic acid modified starch-coated γ-Fe2O3 magnetic nanoparticles [γ-Fe2O3@starchn-butyl SO3H] was easily prepared through a ring opening reaction of 1, 4-butane sultone with nano-magnetic
