Description

Application

Tin(II) chloride dihydrate can be used as a mild Lewis acid catalyst to synthesize:      

• 3-Aminoimidazo[1,2-a]pyridines via three-component condensation reaction of aromatic aldehydes, 2-aminopyridines, and isonitriles.     
• Pyrazolo[5,4-b]quinoline derivatives via cyclocondensation reaction of 5-amino-3-(arylamino)-1H-pyrazole-4-carbonitriles with cyclohexane-1,3-dione or dimedone.    
• Polylactic acid from aqueous lactic acid in the presence of succinic anhydride.

It can also be used as a cocatalyst to synthesize indole derivatives by treating anilines with trialkanolamines in the presence of ruthenium as a catalyst.
