A new straightforward approach to the bridged framework of uleine alkaloids, based on the 6- EXO cyclization of selenoester-derived 3-(tetrahydro-2-pyridyl)-2-indolylacyl radicals under reductive conditions, is described.
描述了一种新的直接方法来构建 uleine 生物碱的桥接框架,该方法基于在还原条件下硒酯衍生的 3-(四氢-2-吡啶基)-2-indolylacyl 自由基的 6-EXO 环化。
