Ionic Liquid Mediated Synthesis of Novel tetrahydroimidazo [1,2- a]pyrimidine-6-carboxylate Derivatives

Aminoazole-Based Diversity-Oriented Synthesis of Heterocycles

“…It should be noted, that Thorat et al ( 2013 ) obtained imidazopyrimidines (EtOH-ionic liquid catalyzed, r.t.) with another positional orientation of substituents than in compounds 102b . However, there was not enough data (2D NMR experiments or X-Ray analysis) proving that structure while the structure of azolopyrimidines 102 was proven with the help of X-Ray analysis in cases of heterocycles 102d (Zhao et al, 2013 ) and 102e (Zhao et al, 2014 ).…”

An Efficient and Green Synthesis of Tetrahydrobenzo[b]Pyran Derivatives Using [(EMIM)Ac] at Room Temperature

“…The use of ionic liquid as a catalyst is another green technique used in organic synthesis. Ionic liquid has received considerable attention as an environmentally friendly solvent as well as catalyst [6–8] . Ionic liquids (ILs) own various properties including thermal stability, flammability, low viscosity, low volatility, negligible vapors pressure, and a wide range of solubility.…”

“…Ionic liquid has received considerable attention as an environmentally friendly solvent as well as catalyst. [6][7][8] Ionic liquids (ILs) own various properties including thermal stability, flammability, low viscosity, low volatility, negligible vapors pressure, and a wide range of solubility. Ionic liquids (ILs) own the potential to bring about fundamental and essential changes in synthetic ways by replacing conventional reagents.…”

Ionic Liquid Promoted Regio‐Selective Synthesis of 2‐Methyl amino‐3‐Nitro‐pyrano[3,2‐c]chromen‐5‐ones

“…Recently, a biodegradable ionic liquid [(EMIM)Ac] is used as an efficient catalyst for various organic transformation. [35][36][37][38][39] In persistence to our research work on development in synthesis of bioactive heterocycles using green routes, [40][41][42][43][44][45] in this context a three component cyclo-condensation of 4-hydroxy coumarin (1), aromatic-aldehydes 2 (a-v) and (E)-N-Methyl-1-(methylthio)-2-nitro-ethenamine (NMSM) (3) catalyzed by 20 mol % of [(EMIM)Ac] as catalyst in methanol at reflux condition and at solvent free condition at 80 to 85 °C reported (Scheme 1).…”
