Synthesis of novel tridentate ligand-based palladium catalyst and investigation of its reactivity towards Suzuki, Sonogashira and Heck coupling reactions

We have demonstrated a simple and efficient route for the synthesis of a novel imine based tridentate ligand and its Pd-complex to investigate the C-C cross-coupling reactions, that involve column chromatography purification in only one step. The catalytic activity of the newly synthesized catalyst was studied for the Suzuki, Sonogashira and, Heck cross-coupling reactions under mild conditions....

A novel synthesis of diastereomerically pure spiro- oxindolopyrrolizidines and oxindolopyrrolidines via cycloaddition reactions of azomethine ylides

An efficient one-pot three-component procedure for the synthesis of new chiral spiro oxindolopyrrolidines/pyrrolizidines with highly regio- and diastereo-enantio, selective from 1,3-dipolar cycloaddition of azomethine ylides and chiral menthol-drived trans-cinnamic are described. The mechanism of the reaction is discussed on basis of the assignment of the absolute configuration of one of the cy...

Catalytic Evaluation of Palladium Nanoparticles on Silica-Grafted n-Propyl-Diaza-15-Crown-5 (PNP-SGPDC) in the Heck and Suzuki Reactions

Silica-grafted n-propyl-diaza-15-crown-5 (SGPDC) with immobilized palladium nanoparticles was found as an efficient heterogeneous catalytic system for the Heck and Suzuki coupling reactions and satisfied results were obtained. Different derivatives of aryl halides and alkenes under the Heck reaction were converted to the corresponding products with good efficiency. The presence of elec...

n-Octyl-3-methylpipyridinium bromide ([OMePPy]+Br-): novel ionic liquid to promote green synthesis of polycyclic fused acridines

In this research, various polycyclic fused acridines were synthesized via the highly efficient and green one-step four-component reaction between isatins, dimedone, various amines, and dimethylacetylenedicarboxylates (DMAD/DEAD) in the presence of n-octyl-3-methylpipyridinium bromide ([OMePPy]+Br-) as a newly prepared ionic liquid, in absolute green situations at room temperature under solvent-...
