chalcones with an electron rich group or sterically large groups such as naphthyl on the carbonyl side tend to activate PPARγ. The absence of any strict structural or electronic requirements suggests that the flexibility of the PPARγ ligand binding pocket may allow binding of diverse chalcones with some preference for a slightly larger electron-rich group on the carbonyl side. We predict that further structure-activity

of this solid in the Claisen–Schmidt condensation was studied and high yields were obtained with small amounts of catalyst. The reaction rate depends on the substitution in both benzaldehyde and acetophenone derivatives. The effect of the solvent, as well as the addition of water and ammonium salt, was investigated as well. The catalyst can be easily recovered and efficiently reused.

The modification of natural phosphate (NP) with sodium nitrate by calcination produces an extremely efficient basic catalyst for the Claisen-Schmidt condensation. A large variety of chalcones is easily obtained in high yield at room temperature using only a catalytic amount of NaNO3/NP. (C) 2001 Elsevier Science Ltd. All rights reserved.
