A bifunctional ionic liquid (IL) [DDQM][HSO4] has been designed and explored as a three-way catalyst for the synthesis of 2-phenylquinazolin-4(3H)-ones from anthranilamide benzyl alcohol in 3.5 min incorporating microwave irradiation. Photochemically reaction proceeds 4 h at room temperature thermally 8 120 °C. Further IL-assisted metal, solvent, base free situ oxidation alcohols to aldehydes shows its task specificity. The multifunctionality IL was reestablished with two Wnt pathway antagonists.
For the first time, an ionic liquid mediated nickel catalyzed mild yet efficient protocol has been developed for biaryl synthesis via Suzuki Miyaura Cross coupling (SMC) reactions. The gives...
An efficient oxidative route to quinazolin-4(3H)-ones using common alcohol precursors is critical for the drug industry since existing methodologies inevitably rely on transition metal assistance in step...
An efficient and simple copper catalytic system has been developed for the synthesis of medicinally important 2-substituted quinazoline-4(3H)-ones from 2-aminobenzonitrile benzyl alcohol derivatives additionally quinazolines 2-aminobenzylamine benzaldehyde derivatives. Mild oxidant H2O2 was utilized, providing excellent product yields. The molecular structure one compounds substantiated through SC-XRD. versatility protocol demonstrated gram-scale syntheses.
Abstract A bio‐waste derived catalyst towards the synthesis of 4‐aryl‐NH‐1,2,3‐triazole is reported. Curd whey major by‐product produced from dairy industry which mostly discarded to water or used as fertilizer and animal feed after drying. Here, an efficient for straight forward NH‐1,2,3‐triazoles under very mild condition. Current method highly versatile, inexpensive, offers various in good excellent yields. The solvent‐catalyst combination can be effectively reused up 4 th consecutive...
Abstract A binary mixture of organic salts, also known as ionic liquids, [C 12 mim][Br]:[MPIM][HCOO] denoted BmIL 1 has been explored bifunctional catalyst for the selective synthesis 2‐phenylquinazolin‐4( 3H )‐ones and 2,3‐dihydroquinazolin‐( 1H from same precursors under metal, ligand additive free conditions. The methodology extended to via another pathway different catalytic system. Greener existing drugs reestablished multifunctionality . Gram scale both products, DFT calculations...
A green protocol for the synthesis of a series 5-amino-1,2,3-triazoles from benzyl cyanide and phenyl azide derivatives catalyzed by novel bifunctional ionic liquid [DHIM][OH] under microwave irradiation has been developed.
A multifunctional room temperature ionic liquid [DDQM][TFSI] has been designed and its properties have investigated to be used as an electrolyte.
Abstract A starch capped copper nanoparticles (SCuNPs) promoted solvent free methodology has been developed for oxidative [3+2] azide‐olefin cycloaddition reaction. The reactions employ atmospheric O 2 /DMSO as oxidant to furnish an assortment of disubstituted and trisubstituted 1,2,3‐triazoles. This method is well‐suited not only with acyclic terminal olefins, but also cyclic open chain internal olefins. proposed mechanism was validated the help DFT calculations. triazole formation proceeds...
