TBAI-catalyzed C-N bond formation through oxidative coupling of benzyl bromides with amines: a new avenue to the synthesis of amides

Dhirendra Kumar et al.

Summary: A new green approach for the synthesis of amide was developed through TBAI-catalyzed oxidative coupling of benzyl bromides with amine using tert-butyl hydroperoxide as an oxidant. Various electron-donating and withdrawing groups were subjected to the reaction, leading to the formation of amide in good to excellent yields.

Nano 5% Fe-ZnO: A highly efficient and recyclable heterogeneous solid nano catalyst for the Biginelli reaction

Ravindra Haribhau Waghchaure et al.

Summary: In this study, the synthesis and catalytic application of 5% Fe-ZnO nanocatalyst for the synthesis of 3,4-dihydropyrimidin-2-one derivatives were reported. The structural and morphological features of the synthesized nanocatalysts were investigated using XRD and SEM. The properties of the nanocatalyst, including particle size, crystal lattice structure, and surface area, were determined using various experimental methods. NMR analysis confirmed the structure of the synthesized products. The results demonstrate that 5% Fe-ZnO nanocatalyst is a highly efficient heterogeneous nanocatalyst for the synthesis of 3,4-dihydropyrimidin-2-one derivatives.

Synthesis of a Zirconium Complex of an N,O-type p-tert-Butylcalix[4]arene and Its Application in Some Multicomponent Reactions

Varun Rawat et al.

Summary: The synthesis and characterization of a new octahedral Zr(IV) complex of oxygen-depleted N,O-type calixarene ligand comprising two distal-functionalized pyrazole rings have been reported. The cone shape and structure of the prepared complex were confirmed univocally by single-crystal X-ray diffraction and NMR studies. This complex has been utilized as an efficient catalyst for the synthesis of Biginelli adducts, bis(indolyl)methanes, and coumarins. In addition, a ferrocene-appended bis(indolyl)methane prepared using this catalyst showed promising anticancer activity against the A-172 cell line.

Efficient One-Pot Synthesis of 3,4-Dihydropyrimidin-2(1H)-ones via a Three-Component Biginelli Reaction

Giovanna Bosica et al.

Summary: Multicomponent reactions offer economic and environmental advantages, with the Biginelli reaction being a significant method for synthesizing 3,4-dihydropyrimidin-2(1H)-ones (DHPMs). In this study, silicotungstic acid supported on Ambelyst-15 was used as a catalyst for the Biginelli reaction under solventless conditions, resulting in improved reaction yields.
