“…Ionic liquid supported synthesis (ILSS) has been successfully applied for a number of organic reactions like 1,3-cycloadditions [131], Knoevengeal reaction [60], Suzuki coupling [132], synthesis of thiazolidinones [133], oligosaccharide synthesis [134], and Grieco's multicomponnet synthesis of tetrahydroquinolines [135]. Donga and coworkers described the synthesis of oligonucleotides in solution using a soluble ionic liquid support.…”

Ionic liquids have emerged as an environmentally friendly alternative to the volatile organic solvents. Being designer solvents, they can be modulated to suit the reaction conditions, therefore earning the name "task specific ionic liquids. " Though primarily used as solvents, they are now finding applications in various fields like catalysis, electrochemistry, spectroscopy, and material science to mention a few. The present review is aimed at exploring the applications of ionic liquids in catalysis as acid, base, and organocatalysts and as soluble supports for catalysts.

“…A strategy to use task-specific ionic liquids was developed and applied to the one-pot three-component synthesis of heterocyclic compounds, together with MW irradiation [138]. Imidazolium-based ILs were linked to poly(ethyleneglycol) (PEG), giving matrices to be used for the so called Ionic Liquid Phase Organic Synthesis (IoLiPOS).…”

Abstract:The quest for sustainable processes is becoming more and more important, with catalysis playing a major role in improving atom economy and reducing waste. Organic syntheses with less need of protecting/de-protecting steps are highly desirable. The combination of microwave irradiation, as energy source, with ionic liquids, as both solvents and catalysts, offered interesting solutions in recent years. The literature data of the last 15 years concerning selected reactions are presented, highlighting the importance of microwave (MW) technology coupled with ionic liquids.

“…[160], [161] While there have been multiple synthestic approaches, there is still considerable scope to develop a more environmentally friendy and efficient approach to this scaffold. [162], [163] Lingampalle et al have developed a rapid entry to 4-thiazolidinones via the N-methylpyridinium tosylate [NMP][Ts] cyclocondensation of amines, aromatic ketones, and mercaptoacetic acid. [164], [165] The reaction proceeds via imine formation, followed by rapid cyclocondensation at 120 ºC (Scheme 57).…”
