Die Butenolide (I) reagieren nach Friedel‐Crafts zu den Säuren (III).

Behavior of Some 2(3H)-Furanones Bearing A Chromone Moiety as Alkylating Agents

“…(ii) the nucleophilicity of the solvent, for instance it was found that changing the solvent from benzene to the more nucleophilic solvents toluene and anisole changed the reaction pathway fromintramolecular to intermolecular mode (26) . (iii) the stability of the carbocation intermediate, it was found that a more stable carbocation, being more selective favors the formation of cyclic products via intramolecular alkylation (29) .…”
