Due to the significance of chiral benzoheterocycles, the synthesis of these skeletons draws considerable attention from chemists and remarkable progress has been made in the last few decades. However, most of the methods employ noble transition metals as catalysts. Herein, this review mainly focuses on the facile assembly of enantio-enriched benzoheterocycles via Earth-abundant metal catalysis. To date, numerous methods have been well developed, such as the Ullmann reaction, hydroarylation, borylation or cycloetherification of alkenes, O-H insertion of alpha-diazo esters, tandem arylation of h...
