Iridium-catalyzed hydroalkenylation of conjugated trienes by chelation-assisted alkenyl C–H activation of acrylamides has been demonstrated to produce 1,4,6-trienes atom efficiently with excellent regio- and E/Z selectivities. In contrast, the reaction of benzamides and 1,3,5-trienes proceeds by a tandem hydroarylation of the trienes and cyclization via intramolecular 1,2-addition, providing valuable
通过螯合辅助丙烯酰胺的烯基 C-H 活化,铱催化的共轭三烯加氢烯基化已被证明可以有效地产生 1,4,6-三烯原子,具有出色的区域 -和E / Z选择性。相反,苯甲酰胺和 1,3,5-三烯的反应通过三烯的串联氢芳基化和通过分子内 1,2-加成的环化进行,提供有价值的反式-四氢异喹啉酮衍生物。具有各种功能的各种芳香族和脂肪族 1,3,5-三烯化合物相容,可提供高产率和E / Z的目标产品选择性。成功的克级制备和选择性氢化得到烷基化产物进一步证明了该协议对潜在应用的实用性。
