Supported Fe/Ru catalyzed three-component relay reaction through hydrogen borrowing strategy: Conversion of crude α-hydroxy acids into valuable N-heterocycles

We developed Fe-Ru/γ-Al2O3 relay catalyst to promote the multi-component reaction of biomass derived α-hydroxyl acid and 2,5-dimethoxytetrahydrofuran with 2-nitroaromatic amine, enabling synthesis of quinoxalines from inexpensive starting materials in one...
