Catalytic systems containing p-toluenesulfonic acid monohydrate catalyzed the synthesis of triazoloquinazolinone and benzimidazoquinazolinone derivatives

A variety of quinazolinones are readily prepared via one-pot three-component reaction in good to excellent yields. The desired products were obtained from the reaction of dimedone, various aldehydes with 2-aminobenzimidazole or 3-amino-1,2,4-triazole unde

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

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

A simple, economical, and environmentally benign protocol for the synthesis of [1,2,4]triazolo[5,1-b]quinazolin-8(4H)-one and hexahydro[4,5]benzimidazolo[2,1-b]quinazolinone derivatives

Abstract An efficient synthesis of [1,2,4]triazolo[5,1-b]quinazolin-8(4H)-one and hexahydro[4,5]benzimidazolo[2,1-b]quinazolinone derivatives with good yields is described. This method involves three-component reaction between aldehydes, dimedone, and 3-a

Nano-SiO2: A green, efficient, and reusable heterogeneous catalyst for the synthesis of quinazolinone derivatives

A highly efficient and general method is applied for the multicomponent synthesis of quinazolinone derivatives from cyclocondensation of aromatic aldehydes and dimedone with 2-amino benzimidazole or 3-amino-1,2,4-triazole using nano-SiO2 as a c

A simple, convenient one-pot synthesis of [1,2,4]triazolo/benzimidazolo quinazolinone derivatives by using molecular iodine

A wide variety of quinazolinone derivatives have been synthesized by condensation of 3-amino-1,2,4-triazole and 2-aminobenzimidazole as amine sources, with aromatic aldehydes and dimedone in the presence of 10 mol % of molecular iodine in acetonitrile und
