Substituted Isocoumarins: An Assemble of Synthetic Strategies Towards 3‐Substituted and 3,4‐Disubstituted Isocoumarins

Abstract

AbstractThe versatility of isocoumarin frameworks offers the privilege to access many pharmacological targets. This unique heterocycle core present in many natural products and complex organic molecules contribute to medicinal chemistry as anti‐cancer, anti‐inflammatory and immunomodulatory agents. The attractive properties exhibited by its analogues urged the scientists to explore their synthetic analogues. In regard to the myriads of synthetic methodologies, we have compiled a review update covering all the articles that have been published towards the synthesis of 3‐substituted and 3,4‐disubstituted isocoumarins. Additionally, we have also highlighted a systematic survey of catalytic methods for their synthesis along with their scope towards diverse functionalizations and plausible mechanistic aspects.
