An efficient, mild and environmentally friendly method was developed for the Strecker reaction to synthesize α–aminonitriles in the presence of methyl imidazolium hydrogen sulfate ([Hmim][HSO4]) as an efficient catalyst. These syntheses were performed via a one–pot three–component condensation of aldehydes (or ketones), amines, and trimethylsilyl cyanide under mild and solvent free conditions.

In the present of methylimidazolium hydrogen sulfate, the synthesis of arylidene heterobicyclic pyrimidinones is studied by condensation of aromatic aldehyde, cyclopentanone, and urea or thiourea. Using solvent–free conditions, non–toxic and inexpensive materials, simple and clean work–up, short reaction times and good yields of the products are the advantages of this method.

An efficient, mild and environmentally friendly method was reported for the synthesis of An efficient, mild and environmentally friendly method was reported for the synthesis of pyranopyroles from aryl aldehydes, ethyl acetoacetate, malononitrile and hydrazine hydrate in the presence of catalytic amounts of Methyl imidazolium hydrogen sulfate ([Hmim][HSO4]) as an efficient catalyst. These syntheses were performed via a one–pot four–component condensation in water\ethanol (50%) at 50 ◦C. This method easily provides the coresponding products in good yield and relatively short reaction times. Also the reusability of the catalyst was investigated, the catalyst could be employed four times, although its activity gradually decreased.
