A direct synthesis of 5,6-dihydroindolo[2,1-a]isoquinolines that exhibit immunosuppressive activity
摘要:
Dihydroindolo[2,1-a]isoquinolines were synthesized from tetrahydroisoquinolines and alpha-fluoroaldehydes by a novel two-step procedure. These compounds exhibited significant immunosuppressive activity against IL-2, IL-10 and IFN-gamma. (C) 2009 Elsevier Ltd. All rights reserved.

efficient Mizoroki–Heck/amination cascade reaction of o-dihaloarenes with cyclic imines was realized by combining nickel and a sterically bulky N-heterocyclic carbene ligand. This protocol provides access to a variety of indole[2,1-a]isoquinolines from readily available starting materials. This cascade approach could be applied to produce straightforward synthesis of the natural product cryptowoline.
通过将镍和空间庞大的 N-杂环卡宾配体结合,实现了邻二卤代芳烃与环状亚胺的高效 Mizoroki-Heck/胺化级联反应。该方案提供了从容易获得的起始材料中获得各种吲哚[2,1- a ]异喹啉的途径。这种级联方法可用于直接合成天然产物 Cryptowoline。
