An efficient and green procedure for the synthesis of quinoxaline derivatives using 3,5-bis(Trifluoromethyl)phenylammonium triflate (bfpat) organocatalyst

The application of 3,5-bis(trifluoromethyl)phenylammonium triflate (BFPAT) as a conven-ient new organocatalyst for the synthesis of quinoxaline derivatives is described. In the presence of BFPAT, one-pot synthesis of a wide variety of quinoxaline derivati

Dowex 50W: Mild efficient reusable heterogeneous catalyst for synthesis of quinoxaline derivatives in aqueous medium

An efficient, simple and eco-friendly procedure is reported in presence of heterogeneous Dowex 50W catalyst in aqueous medium under refluxing condition to produce quinoxaline derivatives. Catalyst has participated in condensation reaction between 1,2-diamines and various aromatic 1,2-diketones smoothly with excellent yield of the products in short reaction times. Dowex 50W was used more than five times in this reaction separately and showed an excellent recyclability throughout the reaction.(figure presented).

Synthesis method of quinoxaline heterocyclic derivative

The invention discloses a synthesis method of a quinoxaline heterocyclic derivative. An intermolecular redox reaction and a condensation cyclization reaction are carried out on an o-nitroaniline compound and an o-diol compound under the action of a water-soluble alkali to prepare the quinoxaline heterocyclic derivative in one step. Expensive transition metal catalysts and ligands do not need to beused, the water-soluble alkali is used as an accelerant and can be removed in a water washing manner, so that the product has no transition metal residue, the product is easy to separate, the recovery rate is high, and the method is simple in condition, easy to operate and low in equipment requirement; and the water-soluble alkali is used as the accelerant, so the unique byproduct is water, the atom economy is high, and the method has good research and industrial application prospects.
