  Regiospecific substitution of the carbon–boron bond of tris(4-trimethylsilylfuran-3-yl)boroxine and tris(4-methylfuran-3-yl)boroxine. Model approaches towards sesquiterpenoid furanoeudesmanes

  摘要：

  Furan-containing compounds occur abundantly in nature. Among them, the sesquiterpenoid furanoeudesmanes are particularly interesting due to their allergenic, plant-growth inhibiting, antibacterial as well as antitumor properties. Recently an organoboron protocol has been developed in our laboratory for the preparation of regiospecific-substituted furans. By utilizing such methodology, two common intermediates 1 and 2 that may lead to the synthesis of naturally occurring tubipofuran (3) furanoeudesm-4-ene (4) and furanoeudesma-1,4-dien-6-one (5) were obtained.
