HAT-Initiated Fragmentation of 4-(Dimethylamino)-1-((3-methylbut-2-en-1-yl)oxy)-3-phenylbut-3-en-2-one

An alkene-tethered enaminone 7 was synthesized in four steps from bromoacetic acid and 3,3-dimethylallyl alcohol. The enaminone was fully characterized, including UV-Vis spectra. TBADT-catalyzed HAT of the alkene-tethered enaminone initiated a fragmentation that yielded the literature-known phenylacetone-derived enaminone.
