An environmentally benign protocol has been developed for the synthesis of two biologically important N-heterocycles i.e. 2,3-dihydroquinazolin-4(1H)-ones and NH-1,2,3-triazoles. These N-heterocyclic compounds are synthesized by readily available inexpensive LiClO4 in ethylene glycol (EG) PEG-400 with good to excellent product yield providing an benchmark rapid these heterocycles under operational simplicity. Sc-XRD one products gives structural information DFT calculations provide on...
Regioselective synthesis of 1,2,3-triazoles has emerged as a cornerstone modern synthetic chemistry, offering immense potential in pharmaceuticals, materials science, and functional applications. This account focuses on advancing click reaction, with majority the innovations stemming from our group’s contributions. Highlights include development novel catalytic systems, both homogeneous heterogeneous exploration copper-free photocatalytic methodologies. bridges traditional approaches,...
Abstract A copper acetate monohydrate catalyzed simple, effective and economic protocol has been developed for the construction of quinazoline derivatives via acceptorless dehydrogenative coupling easily available 2‐aminoaryl methanols nitriles. The methodology was also highly synthesis medicinally important quinolines analogues. reactions proceeded in presence KO t Bu toluene at 110 °C 5 h without requirement inert condition, external additives ligands.
