General description
Benzylideneacetone is used in the fragrance industry for its sweet pea-like odor. It is one of the major constituents of Monanthotaxis capea essential oil. Studies suggest that apart from skatole and androstenone, benzylideneacetone may also be one of the volatile compounds, which contributes to the development of boar taint in fat samples.

An efficient and easy procedure to synthesize the pyridinyl analogues of dibenzylideneacetone (pyr-dba) was developed by the condensation of substituted nicotinaldehyde and acetone in the presence of K(2)CO(3) in toluene-EtOH-H(2)O solvent system. Structurally diverse pyr-dba, including quinolinyl dba, can be
