Highly active nano-MgO catalyzed, mild, and efficient synthesis of amidines via electrophilic activation of amides

Microwave-assisted MgO NP catalyzed one-pot multicomponent synthesis of polysubstituted steroidal pyridines

MgO NPs were proved to be a highly efficient catalyst for mild and clean conversion of steroids to steroidal heterocycles.

Intramolecular alkene hydroamination and degradation of amidines: divergent behavior of rare earth metal amidinate intermediates

The methods for catalytic intramolecular alkene hydroamination and degradation of amidines have been established. Furthermore, a tandem reconstruction/cyclization of amidines has also been developed.

Nano-K2CO3: preparation, characterization and evaluation of reactive activities

Nano-K₂CO₃ shows higher basicity and can replace sodium (potassium) alkoxide to carry out monoalkylation and oximation of active methylene compounds.

A convenient ‘NOSE’ approach used towards the synthesis of 6-amino-1,3-dimethyl-5-indolyl-1H-pyrimidine-2,4-dione derivatives catalyzed by nano-Ag

Uracil derivatives were synthesized in high yield catalyzed by reusable nano-Ag at 70 °C upon reacting 6-amino-1,3-dimethyluracil and indole derivatives.

Palladium-catalyzed three-component reaction of N-tosyl hydrazones, isonitriles and amines leading to amidines

A palladium-catalyzed three-component reaction between N-tosyl hydrazones, aryl isonitriles and amines was developed, leading to amidines in moderate to good yields. This procedure features the rapid construction of amidine frameworks with high diversity and complexity. Ketenimines serve as intermediates, which encounter nucleophilic attack by amines to produce amidines.
