Recent Progress in the Catalytic Synthesis of Pyrrolo[1,2‐α]quinoxaline

Abstract

AbstractPyrrolo[1,2‐α]quinoxaline and its derivatives have excellent biological activity and photoelectric properties, and are widely used in the fields of pharmaceutical preparations and organic electroluminescence. This review starts from catalysts and summarizes the single metal catalysis of palladium, rhodium, iron, molybdenum, and copper, as well as the synergistic catalysis of iron molybdenum bimetallic and metal‐free catalytic systems for the synthesis of pyrrolo[1,2‐α]quinoxaline. The pyrrolo[1,2‐α]quinoxaline catalytic mechanism in the different catalytic systems was detailly introduced and analysed. By analysing the advantages and disadvantages of existing catalyst systems, the prospects of new catalysts and methods for synthesis of pyrrolo[1,2‐α]quinoxaline are presented.
