In a one-pot reaction, three new 2,3-diaminomaleonitrile (DAMN) derivative dyes were prepared by simple Schiff base reaction. The compounds were designed as a sensitizer in dye synthesizes solar cells (DSSCs). Many conditions have been used to provide the... see more

A highly enantioselective organocatalytic Wolff rearrangement–amidation–Michael–hemiaminalization stepwise reaction is described involving a cyclic 2-diazo-1,3-diketone, primary amine and a,ß-unsaturated aldehyde. Product stereocontrol can be achieved by ... see more

During the last decade, the combination of different metal- and bio-catalyzed organic reactions in aqueous media has permitted the flourishing of a variety of one-pot asymmetric multi-catalytic reactions devoted to the construction of enantiopure and high... see more

Silica functionalized with sulfonic acid catalyst (SiO2-SO3H) was synthesized through a one-pot method and evaluated as the catalyst material for esterification of levulinic acid in an excess amount of ethanol. Sodium silicate solution was used as the sil... see more

A highly versatile and convenient synthetic route for biologically act­ive a-amino acid, glutamic acid catalyzed facile and mild preparation of poly­functionalized dihydro-2-oxypyrroles via one-pot, four condensation dom­ino reaction between aromatic/alip... see more

The production of bio-diesel fuels from carbohydrates is a promising alternative to fossil fuels with regard to the growing severity of the environmental problem and energy crisis. Potential bio-diesel candidates or additives, such as 5-(hydroxymethyl)-2-... see more

Nanomagnetic Fe3O4@SiO2@ZnCl2 was used as a simple, cost-effective, and reusable heterogeneous catalyst for the synthesis of 2,6-diamino-4-arylpyridine-3,5-dicarbonitriles by a one-pot-three-component condensation reaction of malononitrile, ammonium aceta... see more

Potato ( Solanum tuberosum L.) cultivar IPB CP1 is suitable as a raw material for the potato chip industry. Potato plants are sensitive to various abiotic stresses such as drought, aluminium and salinity, which induce reactive oxygen species (ROS). ROS i... see more
