Recent development for enantioselective synthesis of aromatic compounds from alkynes via metallacyclopentadienes

Metallacyclopentadiene, which is recognized as a metallo‐heterocycle, is an important intermediate for the formation of aromatic derivatives. In this short review, we summarized the recent advance on construction of axial, central, planar, and helical chirality by transition‐metal‐catalyzed aromatic compounds formation via metallacyclopentadienes.
