THE STUDY OF CROSSED ALDOL CONDENSATION AT THE SYNTHESIS OF ASYMMETRIC DIBENZALACETONE

Abstract

The synthesis of asymmetric dibenzalacetone has been done by crossed aldol condensation. It can be made from 3,4-dimethoxybenzaldehyde, benzaldehyde and acetone as the starting materials. As a nucleophile, acetone, has α-hydrogens in two side. It means, that it can attack two kinds of aldehyde. The product will be characterized by 1H-NMR, 13C-NMR, HMQC and HMBC spectrometer. Therefore, it was identified as 1(E),4(E)-1-phenyl-5-(3’,4’-dimethoxyphenyl)-penta-1,4-diene-3-one. FMIPA, 2008 (PEND. KIMIA
