Mannich Reactions and Its Application in Organic Synthesis

Mannich reactions with aromatic,aromatic ketones and aromatic aldehydes and their applications were studied systematically.In this article,a novel type of Mannich reactions of aliphatic methylketone with aromatic aldehydes and aromatic amines were directly performed at about room temperature or slightly below,in the presence of concentrated hydrochoric aicd as the catalyst.More than ten related Mannich bases, 1-aryl-1-arylamino-3-hexanone were synthesized with the yields being from 61.3%～90.4%. Among the propared Mannich bases,there were eleven new Mannich Base compounds.Various factors to influence the reaction rates and synthetic yields were examined as well.
