TL;DR: In this paper, it was shown that polychlorinated bicyclo-[2.2] oct-5-en-2-ones undergo Diels-Alder reactions when the compounds were heated with such dienophiles as acrylic acid, methyl acrylate, methyl vinyl ketone, acrylonitrile, and ethyl vinyl ether.
Abstract: 2,3,4,5,6,6-Hexachloro-, 2,3,4,6,6-pentachloro-, and 2,4,6,6-tetrachloro-2,4-cyclohexadienones were found to undergo Diels-Alder reactions when the compounds were heated with such dienophiles as acrylic acid, methyl acrylate, methyl vinyl ketone, acrylonitrile, and ethyl vinyl ether. It was concluded, chiefly through analysis of these NMR spectra, that the reactions proceed stereospecifically to give a series of 7-substituted and polychlorinated bicyclo-[2.2.2] oct-5-en-2-ones, which is in agreement with the endo rule. The stereospecificity of these adducts does not, however, agree with the results of calculations by means of the perturbation method.

TL;DR: In this article, cyclic organoboranes react with methyl vinyl ketone to provide a new route to ω-hydroxy-ketones, which is a route for ω -hydroxy ketones.

TL;DR: Silica gel-mediated Michael addition of 1,3-dicarbonyl compounds to methyl vinyl ketone and EVK was carried out to give the corresponding adducts in quite excellent yields as mentioned in this paper.

TL;DR: In this paper, thermal stability and degradation behavior of VB and VB-MVK copolymers spanning the whole composition range were studied using thermogravimetric analysis.

TL;DR: The structure of the clavularins A and B were shown to be cycloheptenone derivatives (2a and B) in this paper, using the Michael reaction of the lithium dienolate anion with trimethylsilyl -substituted methyl vinyl ketone.
Abstract: (±)- Clavularin B (2b) was prepared from cyclohepta-2,6-dienone (4) via a Michael reaction of the lithium dienolate anion (5a) with the trimethylsilyl -substituted methyl vinyl ketone (11). The structures of the clavularins A and B were thus unambiguously established as cycloheptenone derivatives (2a) and (2b). The Mukaiyama reaction between the silyl dienol ether (5b) and but-3-en-2-one gave 8-acetyl-4- methylbicyclo[3.2.2]nonan-6-one (9).
