  Highly Asymmetric Bromocyclization of Tryptophol: Unexpected Accelerating Effect of DABCO-Derived Bromine Complex

  摘要：

  Highly asymmetric bromocyclization of tryptophol by using chiral anionic phase-transfer catalyst and DABCO-derived brominating reagent is described. Optimization of the reaction conditions revealed that the reaction rate was accelerated together with improvement of enantioselectivity by addition of catalytic DABCO-derived brominating reagent. From tryptophol, 3-bromofuroindoline could be directly obtained in excellent enantioselectivities by employing this novel methodology.

  environmentally friendly and efficient protocol (KX/oxone) for oxidative halocyclization of tryptamine/tryptophol derivatives was developed and demonstrated with 28 examples and concise total synthesis of cyclotryptamine alkaloid protubonines A and B. The distinct advantage of this protocol over all previous methods is that no organic byproduct is generated from a halogenating agent or oxidant, thus greatly reducing

  开发了一种环境友好，高效的方案，用于色胺/色氨酸衍生物的氧化卤代环化反应，并通过28个实例进行了证明，并简明地合成了环色胺生物碱A和B的全合成。与所有先前方法相比，该方案的独特优势在于：卤化剂或氧化剂不会产生有机副产物，因此大大降低了卤代环化对环境的影响，并促进了反应后的纯化。

  nucleophilic bromination at the C5-position of tryptophol and tryptamine derivatives is difficult and remains unexplored. Herein, we report a tunable water-mediated electrooxidative protocol for the dearomative C3/C5-bromocyclization of tryptophol and tryptamine derivatives. This electrosynthetic approach enables selective construction of cyclic 3a- or 5a-bromoindolines simply by the addition of different

  由于吲哚部分的 C3/C2 位置的电子富集，色氨酸和色胺衍生物的 C5 位置的直接亲核溴化是困难的并且仍未探索。在此，我们报告了一种可调节的水介导的电氧化方案，用于色氨酸和色胺衍生物的去芳烃 C3/C5-溴环化。这种电合成方法只需添加不同量的水即可选择性地构建环状 3a-或 5a-溴二氢吲哚，无需额外的电解质、外部氧化剂或添加剂。更少的水提供环状 3a-溴二氢吲哚，而更多的水则提供 5a-溴二氢吲哚。
