In this study, topological resonance energy (TRE) methods and ring current (RC) methods were used to describe the global aromaticity of a series of polycyclic neutral oxocarbon isomers. The observed trends in aromaticity are explained. Our results obtained using the TRE method are compared with those obtained using the nucleus independent chemical shift (NICS) method as reported in the literature. The bond resonance energy (BRE) and circuit resonance energy (CRE) indices were applied to study the local aromaticity of oxocarbons. The aromaticity of the individual rings of each of the polycyclic neutral oxocarbon isomers studied was assessed using the Hückel–London ring current (RC) model. The results regarding the local aromatic and antiaromatic states of the individual rings as obtained using the BRE and CRE indices show direct correspondence with the RC results, which indicate the strength of the diatropic and paratropic currents within those rings.

Regio‐ and Stereoselective Synthesis of Rotationally Hindered C₁₂‐Naphthylated Tribenzo[a,c,j]xanthenes through Catalytic Tricyclization of Yne‐Allenones

A Lewis acid‐catalyzed tricyclization of yne‐allenones with 1‐alkynylnaphthalen‐2‐ols has been developed, and used to produce a wide range of rotationally hindered tribenzo[a,c,j]xanthenes with generally good yields and stereoselectivity. This process involves a complex [2+2] cycloaddition relay and [4+2] cyclization cascade, enabling scission/recombination of C−C triple bonds to access unprecedented hexaheterocyclic architectures. The reaction also features good compatibility with different types of substituents, triple annulation cascade and the efficient control of regio‐ and stereochemistry.
