Unexpected novel rearrangement reaction: Synthesis of benzo-medium-ring anhydride

When we attempted to synthesize (E)-3-(benzo[d][1,3]dioxol-5-ylmethylene)- 4-(propan-2-ylidene)-dihydrofuran-2,5-dione, we found a novel rearrangement and obtained the unexpected compound that is assigned as benzo-medium-ring anhydride instead of the expected compound. We described the novel rearrangement and a potential method for the synthesis of benzo-medium-ring anhydride derivatives. Copyright Taylor & Francis Group, LLC.
