Gold-catalyzed cascade cyclization of diynes for the synthesis of previously unexplored C–N axially chiral N-arylbenzo[g]indoles was described. The transformation was achieved via a central-to-axial chirality conversion strategy. The chiral conversion exhibited high efficiency. Besides single C–N chiral axis, N-arylbenzo[g]indoles bearing both C–N and C–C chiral axes were also afforded. The title compound
描述了金催化二炔级联环化,用于合成先前未探索的 C-N 轴向手性N-芳基苯并[ g ]吲哚。这种转变是通过中心到轴的手性转换策略实现的。手性转化表现出高效率。除了单一的C-N手性轴外,还提供了带有C-N和C-C手性轴的N-芳基苯并[ g ]吲哚。制备了标题化合物衍生的单膦配体,并在 Pd 催化的不对称烯丙基取代中进行了评估,显示出优异的手性诱导能力。
