Application

4-Cyanophenylboronic acid can be used as a reactant in:
  • Palladium-catalyzed Suzuki-Miyaura cross-coupling in water.
  • Ruthenium catalyzed direct arylation of benzylic sp3 carbons of acyclic amines with arylboronates.
  • Ligand-free copper-catalyzed coupling of nitro arenes with arylboronic acids.
  • Ferric perchlorate-promoted reaction of fullerenes with various arylboronic acids to give fullerenyl boronic esters.
  • Phosphine-free Suzuki-Miyaura cross-coupling.
  • Palladacycles as effective catalysts for multicomponent reaction with allylpalladium-intermediates.
  • Chan-Lam-type Cu-catalyzed S-arylation of thiols.
  • Regioselective cross-coupling reactions under modfied Suzuki and Still cross-coupling reactions with copper catalysis.
  • Metal-free biaryl coupling reaction in the presence of dimethyl carbonate as a solvent.
  • Suzuki-type cross-coupling reaction with pentavalent triarylantimony diacetates in the absence of a base.

It can also be used to prepare:
  • Himbacine analogs as thrombin receptor antagonists and potential antiplatelet agents.
  • Trisulfonated calixarene upper-rim sulfonamido and their complexation with trimethyllysine epigenetic mark.
  • Antimalarial compounds via Suzuki cross-coupling.
  • Deoxyuridine derivatives.
Reactant involved in:
  • Oxidative hydroxylation
  • Trifluoromethylation
  • 1,4-Addition reactions

Precursor in the synthesis of inhibitors such as:
  • Tpl2 kinase inhibitors
  • P2X7 antagonists used in the treatment of pain

2-[5-(4-Amidinophenyl)-furan-2-yl]-5,6,7,8-tetrahydro-imidazo[1,2-a]pyridine-6-carboxamidine acetate salt (7) was synthesized from 2-[5-(4-cyanophenyl)-furan-2-yl]-imidazo[1,2-a]pyridine-6-carbonitrile (4a), through the bis-O-acetoxyamidoxime followed by hydrogenation in glacial acetic acid. Compound 4a was obtained in four steps starting with two successive brominations of 2-acetylfuran first with N-bromosuccinimide, and second with bromine

A novel class of orally active antimalarial 3,5-diaryl-2-aminopyridines has been identified from phenotypic whole cell high-throughput screening of a commercially available SoftFocus kinase library. The compounds were evaluated in vitro for their antiplasmodial activity against K1 (chloroquine and drug-resistant strain)
