Efficient biogenesis of Cu2O nanoparticles using extract of Camellia sinensis leaf: Evaluation of catalytic, cytotoxicity, antioxidant, and anti-human ovarian cancer properties

At the moment, metallic nanoparticles especially copper nanoparticles are administrated for the cure of different disorders, such as tumor and cancer. In recent years, many chemotherapeutic supplements have been formulated by copper nanoparticles. In the

Nickel NPs @N-doped titania: an efficient and recyclable heterogeneous nanocatalytic system for one-pot synthesis of pyrano[2,3-d]pyrimidines and 1,8-dioxo-octahydroxanthenes

Abstract: Catalysis holds a very important and promising place in chemical industry. In a typical chemical transformation, the use of a catalyst reduces the reagent-based waste and enhances the reaction selectivity, thereby minimizing the chances of getti

Butane-1-sulfonic acid immobilized on magnetic Fe3O4@SiO2 nanoparticles: A novel and heterogeneous catalyst for the one-pot synthesis of barbituric acid and pyrano[2,3-d] pyrimidine derivatives in aqueous media

Butane-1-sulfonic acid immobilized on magnetic Fe3O4@SiO2 nanoparticles (Fe3O4@SiO2-Sultone) was easily prepared via direct ring opening of 1,4-butanesultone with nanomagnetic Fe3O4@SiO2. The prepared reagent was characterized and used for the efficient promotion of the synthesis of barbituric acid and pyrano[2,3-d] pyrimidine derivatives. All reactions were performed under mild and completely heterogeneous reaction conditions affording products in good to high yields. The catalyst is easily isolated from the reaction mixture by magnetic decantation and can be reused at least eight times without significant loss in activity.

4-(4-Propylpiperazine-1-yl)butane-1-sulfonic acid-modified silica-coated magnetic nanoparticles: A novel and recyclable catalyst for the synthesis of 5-arylidinebarbituric acids and pyrano[2,3-d]pyrimidinedione derivatives in aqueous media

A mild, simple and efficient procedure for the preparation of barbituric acid and pyrano[2,3-d]pyrimidine derivatives in aqueous media is described using 4-(4-propylpiperazine-1-yl)butane-1-sulfonic acid-modified silica-coated magnetic nanoparticles as a novel and reusable catalyst. The catalyst was easily isolated from the reaction mixture by magnetic decantation using an external magnet and reused at least eight times without significant degradation in activity.

Green cellulose-based nanocomposite catalyst: Design and facile performance in aqueous synthesis of pyranopyrimidines and pyrazolopyranopyrimidines

A cellulose-based nanobiocomposite decorated with Fe3O4 nanoparticles was prepared, characterized and applied as an easily recoverable and reusable green nanocatalyst in the synthesis of pyrano[2,3-d]pyrimidine derivatives in water a

CYCLIZATION OF NITRILES. XVI. REACTION OF ARYLIDENE DERIVATIVES OF MALONONITRILE AND ETHYL CYANOACETATE WITH BARBITURIC ACID

The synthesis of 7-amino-5-aryl-6-cyano- and 6-ethoxycarbonyl-5H-pyranopyrimidine-2,4(1H,3H)-diones was realized by the reaction of the arylidene derivatives of malononitrile and ethyl cyanoacetate with barbituric acid.
