Indole frameworks via transition-metal-free annulation: a current perspective

Abstract

The present review summarizes recent (2019–mid-2023) efforts towards the construction of the indole core via transition-metal-free methods.

Synthesis of indazole-based fluorophores

Abstract

The indazole scaffold, with its planar, π-conjugated structure, enables extensive derivatization and tunable luminescence. This makes it ideal for sensing, bioimaging, and materials science, including applications like cell staining and drug development.

Abstract

The emergence of drug-resistant viruses continues to be an obstacle to effectively controlling the HIV/AIDS pandemic.

A review on indole synthesis from nitroarenes: classical to modern approaches

Abstract

This review surveys traditional and modern methods for synthesizing indoles from nitroarenes, including one-pot, tandem, cycloaddition, photochemical, and electrochemical strategies for efficient access to functionalized indoles.
