The title catalyst is successfully applied on the multicomponent reaction of amines, nitroolefin, and 1,3-dicarbonyl compounds. The heterogeneous magnetic catalyst can be easily recovered and reused five times without significant loss of its activity. -(LI, B.-L.; HU, H.-C.; MO, L.-P.; ZHANG*, Z.-H.; RSC Adv. 4 (2014) 25, 12929-12943, http://dx.doi.org/10.1039/c3ra47855f ; Coll.

Pyrroles. -A deep eutectic solvent based on choline chloride and malonic acid is used as a dual catalyst and green reaction medium for the synthesis of a wide range of functionalized pyrroles by four-component reaction of various amines, aldehydes, 1,3-dicarbonyl compounds, and nitromethane. The solvent is reusable three times without significant loss of activity. -(HU, H.-C.; LIU, Y.-H.; LI, B.-L.; CUI, Z.-S.; ZHANG*, Z.-H.; RSC Adv. 5 (2015) 10, 7720-7728, http://dx.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
