Abstract

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

用于制造苯并芴的炔烃单元级联环化的最新进展

苯并芴是一类重要的多环芳烃（PAHs），在材料科学中被广泛应用于光敏电子元件。此外，苯并芴骨架也是各种天然产物的关键结构单元。因此，开发构建苯并芴的合成策略一直是合成化学领域的一个突出研究课题。在过去的几十年中，人们为通过炔烃单元的级联环化来构建苯并芴做出了大量努力。本综述旨在总结炔烃单元级联环化在构建苯并芴方面的最新进展。根据这些转化的不同反应机理，本综述可分为四类：(1) 热诱导的炔烃单元级联环化以构建苯并芴，(2) 金属催化的炔烃单元级联环化以构建苯并芴，(3) 酸促进/催化的炔烃单元级联环化以构建苯并芴，以及 (4) 碱促进的炔烃单元级联环化以构建苯并芴。

期刊介绍： Advanced Synthesis & Catalysis (ASC) is the leading primary journal in organic, organometallic, and applied chemistry. The high impact of ASC can be attributed to the unique focus of the journal, which publishes exciting new results from academic and industrial labs on efficient, practical, and environmentally friendly organic synthesis. While homogeneous, heterogeneous, organic, and enzyme catalysis are key technologies to achieve green synthesis, significant contributions to the same goal by synthesis design, reaction techniques, flow chemistry, and continuous processing, multiphase catalysis, green solvents, catalyst immobilization, and recycling, separation science, and process development are also featured in ASC. The Aims and Scope can be found in the Notice to Authors or on the first page of the table of contents in every issue.
