以焦性没食子酸、4-羟基苯甲醛和酚为原料, 以邻碘代苯酚与苯乙炔衍生物的Sonogashira偶联及其连串化反应生成苯并呋喃环为关键步骤, 设计合成了一系列2-(2 ,6 -二烷氧基苯基)苯并呋喃衍生物, 并对产物进行了1H NMR, 13C NMR, MS等表征.

关键词: Sonogashira偶联, 2-苯基苯并呋喃, 苯并呋喃, Lespedezavirgatol

Starting from pyrogallic acid, 3,4-dimethoxyphenol, 4-hydroxybenzaldehyde and phenols, a series of 2-(2 ,6 -dialkoxyphenyl)-benzo[b]furan derivatives were designed and synthesized. The Sonogashira cross-coupling of o-iodophenol and aryl acetykenes was the key step of the synthetic route. All the new benzo[b]furan derivatives were confirmed by 1H NMR, 13C NMR and MS techniques.

Key words: Sonogashira cross-coupling, 2-phenylbenzo[b]furan, benzo[b]furan, lespedezavirgatol
