Abstract Various polysubstituted benzofurans were reduced by using triethylsilane in trifluoracetic acid. 2,3-Dihydrobenzofurans or bibenzyl compounds were obtained in high yields, depending on the nature of the substituents at C2 and on the benzene ring of the core structure. A p-anisole substituent at C2 of benzofurans always led to the corresponding bibenzyls. Publication History Received: 09 September
摘要 通过在三氟乙酸中使用三乙基硅烷还原各种多取代的苯并呋喃。取决于C2处取代基的性质以及核心结构的苯环,可以高收率获得2,3-二氢苯并呋喃或联苄化合物。甲p在苯并呋喃的C2 -苯甲醚取代基总是导致了相应的联苄类。 出版历史 收到:2020年9月9日 修订后接受:2020年9月30日 发布日期: 2020年10月22日(在线) ©2020年。Thieme。版权所有 Georg Thieme Verlag KGRüdigerstraße14,70469斯图加特,德国
