  单电子转移产生的超氧离子对N-杂环的脱氢作用

  摘要：

  在许多药物，天然产物和合成材料中都发现了含氮杂芳烃基序。尽管已经报道了几种通过相应的饱和杂环的脱氢合成这些化合物的优美方法，但是其中一些方法因反应时间长，苛刻的条件以及对催化剂的需求而难以获得。这项工作报告了一种新的N-杂环脱氢方法。具体而言，原位生成的O 2 .-充当N杂环底物的氧化剂，这些底物易受氢原子转移机制的氧化。这种方法为通向N-杂芳烃提供了一条通用的绿色路线。

  摘要：

  In the course of studies directed toward the discovery of novel acetyl- and butyrylcholinesterase (AChE and BChE) inhibitors for the treatment of Alzheimer's disease, we focused on beta-carbolines (BCs). 6-Oxygenated P-carboline and P-carbolinium derivatives based on the serotonin template were synthesized and tested in vitro for their ability to inhibit AChE and BChE, respectively. Particularly the carbolinium salts, which can be formed by intracerebral methylation out of the tertiary-BC prodrugs, show inhibitory activity levels reaching those of galantamine, physostigmine, and rivastigmine.

  Abstract A new strategy to 2-aminochromanes through catalyst-free cascade reaction of 3-trifluoroacetyl-4H-chromenes and 4H-chromene-3-carbaldehydes with cyclic secondary amines is presented. The reaction proceeds through subsequent 1,4- and 1,2-additions of amine, bimolecular elimination of trifluoroacetamide or formamide, and 6-exo-trig cyclization. The latter stage is a very rare example of addition
