Indium Triflate's Transformative Role in Modern Organic Synthesis: A Five‐Year Survey of Functionalization, Cyclization, and Multicomponent Reactions

Indium triflate (In(OTf)3) has proven to be a powerful and sustainable catalyst in the synthesis of modern organic compounds, enabling a variety of transformations such as functionalization, cyclization, and multicomponent reactions. To provide insight into the most recent methods and applications, this study attempts to provide a comprehensive and up‐to‐date summary of these advances in the application of indium triflate as a catalyst in organic synthesis, focusing on the last five years of literature. The application of indium triflate as opposed to alternative indium(III) catalysts in organic transformations will be the main emphasis of this review, which will cover recent developments through research articles and reviews published between 2019 and 2023. This minireview will make a significant contribution to the existing literature by consolidating recent advancements in the use of indium triflate in modern organic synthesis. This review is esteemedly dedicated to my doctoral advisor, Professor Yong Rok Lee. I am privileged to have been granted the opportunity to conduct research on indium triflate catalysis by him, which has enabled me to undertake and compile this scholastic endeavor. This visual summary highlights the key theme of the proposed review article; Indium Triflate's Transformative Role in Modern Organic Synthesis: A Five‐Year Survey of Functionalization, Cyclization, and Multicomponent Reactions.
