- 論文の詳細を見る
The treatment of 2-methylfuran with phosphoric acid yields the 2,4,4-tris(5′-methyl-2′-furyl)-1-pentanol (<B>1</B>) as a tetrameric product. This product gives its acetate (<B>2</B>) on acetylation with acetic anhydride, and forms a equimolar adduct (<B>3</B>) after treatment with maleic anhydride. The structural formula of <B>1</B> is supported by the IR, UV, NMR, and mass spectral data and by the other experimental facts. The other oligomers are separated as a product (<B>4</B>) which contains tetra-, penta-, hexa-, and heptamer. The structure of these oligomers discussed, and some possible reaction mechanisms for oligomerization are suggested.
