TLDR
In this article, the synthesis and Claisen rearrangement of methyl γ-aryloxycrotonates have been investigated and a number of them have been successfully rearranged to a mixture of Z and E 3-ethylidenebenzofuran-2(3H)ones in refluxing ethylene glycol.
Abstract: 
The synthesis and Claisen rearrangement of methyl γ-aryloxycrotonates have been reinvestigated. A number of methyl γ-aryloxycrotonates have been prepared and sucessfully rearranged to a mixture of Z and E 3-ethylidenebenzofuran-2(3H)ones in refluxing ethylene glycol.
