在氮杂环卡宾(NHC)催化下, α,β-不饱和醛与3-烯基氧化吲哚化合物的[3+2]环加成反应, 高效生成了含一个螺碳中心的连续三个立体中心的环戊酮-螺环氧化吲哚. 该反应具有良好的底物普适性, 获得了中等到良好的产率(43%~78%)和优异的非对映选择性(>20∶1 dr). 此外, 反应还具有反应条件温和、操作简便的优点, 并且克级反应也能顺利进行. 该工作为高效构建官能团化的环戊酮-螺环氧化吲哚化合物提供了新的合成方法学.

Under N-heterocyclic carbene (NHC) catalysis, a [3+2] cycloaddition reaction between α,β-unsaturated aldehydes and 3-alkenyl oxindoles efficiently constructed spirooxindole-fused cyclopentane derivatives with three contiguous stereocenters including one spirocarbon center. This transformation demonstrates broad substrate scope, delivering products with moderate to good yields (43%~78%) and excellent diastereoselectivity (>20∶1 dr). The protocol features mild reaction conditions, operational simplicity, and scalability to gram-level synthesis. This study establishes a novel synthetic methodology for the efficient construction of functionalized spirooxindole-fused cyclopentanes.

Key words: N-heterocyclic carbene, cycloaddition, 3-alkenyl oxindole, spirooxindole-fused cyclopentane
