This is really frustrating... I have no idea how to aquire any more info on this exciting ACS conference abstract...

Abstract
The Carroll rearrangement, a variant to the ester Claisen rearrangement, is a useful method for preparing ,-unsaturated ketones from allylic acetoacetates. The reaction has found limited action in synthetic organic chemistry due to the harsh thermal conditions normally needed to induce the [3,3]-sigmatropic rearrangement. While examining the chemistry involving allylic acetoacetate I, we encountered a mild (room temperature) Carroll rearrangement that afforded the phenylacetone derivative III via keto-acid II. Several examples showing the generality, scope, and limitations of the methodology will be described along with mechanistic considerations.

Thanks Kurupira! Here's the full article - It was way stranger chemistry than I imagined...
