Quinoxalines are benzopyrazines containing benzene and pyrazine rings fused together. In
the recent past, quinoxalines have attracted Medicinal Chemists considerably for their …

Heterocycles and their derivatives have been inspiring medicinal chemists to device novel,
greener and efficient ways to synthesized them as the majority of drugs available in the …

Base-metal catalyzed dehydrogenative self-coupling of 2-amino alcohols to selectively form
functionalized 2, 5-substituted pyrazine derivatives is presented. Also, 2-substituted …

Via a ruthenium-catalyzed hydrogen transfer strategy, we have demonstrated a one-pot
method for efficient synthesis of quinoxalines from 2-nitroanilines and biomass-derived …

An efficient and convenient homogeneous catalytic system is developed from commercially
available Ru complex ([Ru (p-cymene) Cl 2] 2) and 1, 4-bis (diphenylphosphino) butane …

A novel and facile iron‐catalyzed tandem annulation of o‐phenylenediamines and
diazocarbonyls in water for the construction of polyfunctionalized quinoxalines has been …
