• Pyrano-quinoxaline
• Benzo[f]quinoxaline
• Three- and four-component reaction
• Solvent effect
• Multicomponent reaction (MCR)

A two-step procedure has been used to synthesize quinoxaline derivatives in the presence of a catalytic amount of triethylamine. Products can be separated from the reaction media by simple filtration. When EtOH was used as a solvent, the reaction proceeded via a three-component pathway, but in the presence of MeOH (as a solvent or in a 1-equivalent) the reaction proceeded via a four-component pathway.
