A simple and efficient method has been developed for the one-pot Mannich reaction of β-amino carbonylcompounds from aromatic aldehydes, aromatic ketones and aromatic amines in the presence of a catalytic amount of bismuth trichloride.

Cerium trichloride heptahydrate (CeCl3 center dot 7H(2)O) was found to be an efficient and recyclable catalyst for the three-component direct Mannich reaction of anilines and benzaldehydes with acetophenone. This protocol has advantages of high yield, no environmental pollution, mild condition, and simple work-up procedure. (C) 2009 Chun Xu Lu.
