A facile approach for the synthesis of enantiopure γ-amino nitriles by copper-catalyzed aminocyanation of arylcyclopropanes is disclosed, which undergoes the highly enantioselective ring-opening reaction of cyclopropanes. The strategy utilizes N-fluorobenzenesulfonimide as nucleophilic nitrogen source as well as oxidant and trimethylsilyl cyanide as the other nucleophile, and it probably operates via
公开了通过铜催化的芳基环丙烷的氨基氰化合成对映体纯的γ-氨基腈的简便方法,该方法经历了环丙烷的高度对映选择性的开环反应。该策略利用N-氟苯磺酰亚胺作为亲核氮源,同时使用氧化剂和三甲基甲硅烷基氰化物作为其他亲核体,它可能通过关键的自由基阳离子中间体进行操作。该反应提供了用于环丙烷的不对称1,3-双官能化的有效平台。
