Abstract Benzofluorenes are an important class of polycyclic aromatic hydrocarbons (PAHs), which widely used in materials science for light‐sensitive electronic components. In addition, the benzofluorene skeleton also serves as a key structural unit various natural products. Therefore, development synthetic strategies construction benzofluorenes has been prominent research topic chemistry. Over past few decades, numerous efforts have made via cascade cyclization alkyne units. This review aims to summarize recent advances units Based on different reaction mechanisms underlying these transformations, this can be divided into four categories: (1) thermal‐induced benzofluorenes, (2) metal‐catalyzed (3) acid‐promoted/catalyzed and (4) base‐promoted benzofluorenes.
