From C4 to C7: Innovative Strategies for Site-Selective Functionalization of Indole C-H Bonds

Jian Wen et al.

Summary: The presence of hydrocarbons makes C-H functionalization an attractive alternative, with indole being an important heteroarene. Selective C-H functionalization at the benzene core of indoles is challenging, with efforts focusing on directing group development. Innovative strategies have been developed to selectively functionalize different positions of indoles, offering efficient methods for the synthesis of valuable substituted indoles.

Recent Advances in Metal-Catalyzed Functionalization of Indoles

Kelvin Urbina et al.

Summary: Indole is an important heterocycle in organic synthesis, natural products, and drug discovery, and recent research on the selective functionalization of indole has made significant advances, driven mainly by transition metal catalysis and metal-free methods. Future trends include transition-metal-catalyzed functionalization at different positions and transition-metal-free functionalization.

Tryptophan as a Template for Development of Visible Fluorescent Amino Acids

Arusha Acharyya et al.

Summary: Most biological systems are complex, diverse, and non-fluorescent, requiring the development of diverse fluorescence reporters for studying their structures, dynamics, and interactions without affecting their native properties. Tryptophan-based fluorescent amino acids have been identified as a potential solution for this need, with recent progress and future directions towards their development.

Transition metal-catalyzed C-H functionalizations of indoles

Pravin Kumar et al.

Summary: In the past two decades, significant progress has been made in the research of transition-metal catalyzed C-H functionalization of indoles, particularly in terms of positional-selectivity and site-selectivity. Researchers have successfully achieved the functionalization of indole C-H bonds through strategies such as introducing Lewis-basic directing groups.
