carbon of the bis(phenylsulfonyl)methyl unit to ultimately generate trisubstituted alkenes, comprising formal sp3–sp2 and sp2–sp2 cross‐couplings between organolithium reagents and bis(sulfones). This process occurs almost instantaneously at −78 °C in the absence of any transition metals. By developing this curious transformation, it has been demonstrated that bis(phenylsulfonyl)methane is a valuable

Rh-catalyzed intramolecular condensation of the benzyl azides with α-aryldiazoesters was explored. The reaction proceeded through the nucleophilic attack of the organic azide onto a rhodium carbenoid, while releasing nitrogen gas, affording the α-imino esters as the primary product. Tautomerization of the imino esters efficiently gave 13 desired isoindoles with good to excellent yields.
The present invention relates to a series of Isoquinolone derivatives which are suitable to treat infections with viruses belonging to the family of the Flaviviridae and more preferably infections with Hepatitis C virus (HCV). The present invention also relates to Isoquinolone compounds for use as a medicine for the prevention or treatment of viral infections, preferably infections with viruses belonging to the family of the Flaviviridae.
