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.
γ-芳氧基巴豆酸甲酯的合成和克莱森重排已被重新研究。已经制备了许多γ-芳氧基巴豆酸甲酯,并在回流的乙二醇中成功地将其重新排列成Z和E 3-亚乙基苯并呋喃-2(3H)酮的混合物。
