We present an unprecedented atroposelective [8+2] cycloaddition reaction between pyridinium/isoquinolinium ylides and ynals. It is worth noting that this protocol represents a new example of the organocatalyzed atropoenantioselective higher-order cycloaddition reaction, providing various axial chiral 3-arylindolizines in good yields and high enantioselectivities. In addition, the obtained axially chiral
我们在
吡啶鎓/
异喹啉鎓叶立德和ynals之间提出了前所未有的atroposelective [8+2]环加成反应。值得注意的是,该协议代表了有机催化的 atropoenantioselective 高级环加成反应的一个新例子,以良好的产率和高对映选择性提供各种轴向手性 3-芳基
吲哚嗪。此外,获得的轴向手性 3-芳基多嗪也为结构转变和潜在的药物发现提供了许多机会。
