and arylboronic acids, is described. The sequential reaction sequence involves nucleophilic addition of the sulfonamide to the alkynyl bromide, followed by a palladium-catalyzed tandem intramolecular Heck and intermolecular Suzuki cross-coupling reaction of the bromoalkene adduct. An expedient protocol for the synthesis of 5-aryl-2,3-dihydropyrroles, starting from N-tosyl-protected 2-methylprop-2-en-1-amine
摘要 描述了从N-甲苯磺酰基保护的2-甲基丙-2-烯-1-胺,炔基溴化物和芳基硼酸开始的用于合成5-芳基-2,3-二氢吡咯的简便方法。顺序反应顺序包括将磺酰胺亲核加成到炔基溴化物上,然后进行钯催化的串联分子内Heck分子和溴代烯烃加合物的分子间Suzuki交叉偶联反应。 描述了从N-甲苯磺酰基保护的2-甲基丙-2-烯-1-胺,炔基溴化物和芳基硼酸开始的用于合成5-芳基-2,3-二氢吡咯的简便方法。顺序反应顺序包括将磺酰胺亲核加成到炔基溴化物上,然后进行钯催化的串联分子内Heck分子和溴代烯烃加合物的分子间Suzuki交叉偶联反应。
