A facile and convergent approach has been developed for the stereoselective construction of biologically important polyhydroxylated 2‐acyl indolizidine framework using aza‐Cope rearrangement–Mannich cyclization as a key step. The generality of this methodology is demonstrated with various lactol‐tosylates derived from carbohydrates. The presented method provides an easy access to indolizidine‐ and
已经开发了一种简便且收敛的方法,该方法使用aza-Cope重排-Mannich环化作为关键步骤,对具有生物重要性的多羟基化2-酰基吲哚并咪唑骨架进行立体选择性构建。碳水化合物衍生的各种乳糖醇-甲苯磺酸盐证明了这种方法的普遍性。提出的方法可以轻松获得高产率的基于吲哚并立定和基于四氢吲哚嗪的亚氨基糖衍生物。
