Aldol condensation synthesis of benzalacetophenone.

Experiment 11: Synthesis of Dibenzalacetone by the Aldol condensation Introduction: The Aldol condensation reaction, under basic conditions, involves the nucleophilic addition of an enolate ion to another carbonyl group. The resulting product, a beta-hydroxy ketone or aldehyde, is called an aldol because it contains both and aldehyde group and.

The search for new isobaric markers is focused on developing a more selective method of introducing a tag into a peptide molecule, increasing the multiplexicity of markers, lowering the cost of synthesis, and increasing the sensitivity of measurement by using ionization tags containing quaternary ammonium salts. Here, the trends in the design.
