Journal of the American Chemical Society, 128(5), 1426-1427 (2006-02-02)
The cycloaddition between 1,3-cyclohexadiene and various enones and enals (methyl vinyl ketone, ethyl vinyl ketone, methacrolien) is accomplished at room temperature in yields ranging from 51 to 68% without the use of Lewis acids, high pressures, or microwave reactors. This

Chemical research in toxicology, 4(1), 50-57 (1991-01-01)
The reaction of the alpha, beta-unsaturated ketones methyl vinyl ketone (MVK) and ethyl vinyl ketone (EVK) with nucleosides and 5'-mononucleotides was studied. The genotoxic activity of MVK and EVK in the SOS Chromotest was investigated. Three different types of adducts

Mutation research, 470(1), 29-37 (2000-09-15)
alpha,beta-Unsaturated ketones are bifunctional compounds which form promutagenic 1,N(2)-propanodeoxyguanosine adducts like carcinogenic alpha,beta-unsaturated aldehydes and are mutagenic and genotoxic like these aldehydes. They are important industrial chemicals, are found in our environment and are widespread in our food. We investigated

The release of volatiles from tomatillos (Physalis ixocarpa Brot.) and tomatoes in the mouthspace and nosespace was measured in real-time using selected ion flow tube mass spectrometry (SIFT-MS). (Z)-3-Hexenal, (E)-2-hexenal, hexanal, and 1-penten-3-one increased, while isobutyl alcohol, nonanal, and methylbutanal
