An easy synthetic approach to 1,2,3-triazole-fused heterocycles
摘要:
A convenient synthesis of 1,2,3-triazole-fused isoindolines and dihydroisoquinolines in good to excellent yield is reported, starting from easily available terminal alkynes and (2-haloaryl)alkylazides. The method is based upon a cycloaddition reaction, via click chemistry, followed by a transition metal-catalyzed functionalization of a C-H bond. (C) 2010 Elsevier Ltd. All rights reserved.
Herein we report an efficient procedure for the C–H functionalization of 1,2,3-triazoles in a continuous flow regime applied to a variety of functionalities and to the inter- or intramolecular versions of the process.
A bifunctionalmetalorganicframeworkcatalyst containing palladium and copper(II) benzene‐1,3,5‐tricarboxylate – MOF‐Cu(BTC)‐[Pd] – has been prepared. This catalyst enables the performance of the tandem Sonogashira/click reaction starting from 2‐iodobenzylbromide, sodium azide and alkynes to produce 8H‐[1,2,3]triazolo[5,1‐a]isoindoles with good yields under mild reaction conditions.
制备了一种含钯和铜(II)苯-1,3,5-三羧酸盐(MOF-Cu(BTC)-[Pd])的双功能金属有机骨架催化剂。该催化剂能够从2-碘代苄基溴化物,叠氮化钠和炔烃开始进行串联Sonogashira / click反应,以在温和的反应条件下以良好的收率生产8 H- [1,2,3]三唑[5,1- a ]异吲哚。
