functionalized alkenes in intermolecular Alder–ene reactions with arynes is described. The arynes generated from bis-1,3-diynes react with various trisubstituted and 1,1-disubstituted alkenes containing hydroxyl, amino, halo, carboxyl, boronate, and 1,3-dienyl functionalities, providing product distributions with varying degrees of selectivity between Alder–ene and addition reactions. The geometry of
描述了官能化烯烃在分子间Alder-ene与芳烃反应中的反应性和选择性。由双1,3-二炔生成的芳烃与各种具有羟基,氨基,卤代,羧基,硼酸酯和1,3-二烯基官能团的三取代和1,1-二取代的烯烃反应,从而提供产物选择性不同的分布。 der木烯和加成反应。烯烃的几何形状是二取代和三取代的烯烃的反应性的另一个重要因素,其中顺式配置的烯基系统的烯丙基氢是反应性的,与相应的分子内反应相比,这是相反的反应性。
