Total Synthesis and Structural Determination of XR774, a Tyrosine Kinase Inhibitor

Recent advances in the synthesis and applications of fluoranthenes

As an important subclass of polycyclic aromatic hydrocarbons (PAHs), fluoranthenes continue to attract significant attention in synthetic organic chemistry and materials science. In this article, an overview of recent advances in the synthesis of fluoranthene derivatives along with selected applications is provided. First, methods for fluoranthene synthesis with a classification based on strategic bond disconnections are discussed. Then, the total syntheses of natural products featuring the benzo[j]fluoranthene skeleton are covered. Finally, examples of important applications of a variety of fluoranthenes are summarized.

Benzo[j]fluoranthene-Derived Natural Products

In this overview the literature on benzo[j]fluoranthene-derived toxins produced by fungi is discussed with a view on isolation, structure, biological activities, biosynthesis, and total syntheses of the natural products. This class of compounds consists until now of 33 naturally occurring compounds, where 25 are chiral and eight contain no stereogenic centers. The relative configuration of xylarenol was clarified by comparison of experimental and calculated ECD spectra, and absolute configurations of four toxins were corrected. The compounds show various biological activities including antibiotic and cytotoxic properties.
