苯并[ c ]呋喃是一类有趣的高反应性化合物,易于与亲二烯体进行狄尔斯-阿尔德环加成反应以恢复其芳香性。最初,š被选择用于标题分子的合成通过养兔建立-tetrazine方法。然而,发现用这种方法生产异苯并呋喃的速度太慢而不能与逃犯的芳烃反应。因此,采用了另一种途径以实现纯净状态的标题分子。以这种方式,成功实现了标题分子与芳烃之间的反应。在此,报道了两种用于标题分子的合成方法及其对制备甲硅烷基化的线性多环芳族烃(PAH)的进一步操作。

Benzo[c]furans are a class of interesting compounds. :Being very reactive, they readily undergo Diels-Alder cycloaddition with dienophiles to restore their aromaticity. For this reason, they can be utilized to construct six-membered ring compounds which are common building blocks of many natural and nonnatural molecules. In connection with our use of silylated furans in the preparation of polysubstituted furans, we sought to extend our work to include silylated benzo[c]furans as well. Herein, we report the synthesis of the title molecule and its further manipulation for the preparation of several silylated linear polynuclear aromatic compounds. (C) 2000 Elsevier Science Ltd.

reactive compounds that readily undergo Diels–Alder cycloaddition with dienophiles to restore their aromaticity. Initially, the s-tetrazine approach established by Warrener was chosen for the synthesis of the title molecule. However, it was discovered that the rate of production of isobenzofuran from this approach was too slow to react with the fugitive arynes. Consequently, an alternative route was employed
