Ruthenium-catalyzed benzimidazoisoquinoline synthesis via oxidative coupling of 2-arylbenzimidazoles with alkynes
摘要:
Synthesis of a fused bis-heterocyclic framework, benzimidazoisoquinoline, has been achieved using Ru-catalyzed reaction of alkynes with 2-aryl benzimidazoles in the presence of Cu salts. The method provides an easy access for the generation of a library of benzimidazoisoquinoline derivatives. (C) 2013 Elsevier Ltd. All rights reserved.
The first rhodium‐catalyzed oxidative double C−Hactivation/annulation reaction of amidines and alkynes to construct benzimidazoisoquinolines was developed. The operationally simple transformation showed high functional group compatibility and featured the cleavage of the C−H bonds located on a different moiety of the N‐phenylbenzimidamide substrates.

Late-stage functionalization (LSF) of active pharmaceutical ingredients can provide a straightforward approach to efficient de novo design and synthesis of drug molecules for structural activity relationship studies (SARS). Herein, we have developed a visible-light-driven modular micro-flow reactor consisting of an integrated post-synthetic work-up that was designed and developed to synthesize a fused N-heteroaryl
The present invention relates to metal complexes and to electronic devices, in particular organic electroluminescent devices, comprising these metal complexes.
