Isocyanate-based multicomponent reactions.

Since their discovery, multicomponent reactions have attracted significant attention due to their versatility and efficiency. This review aims to explore the latest advancements in isocyanate-based multicomponent reactions and the sophisticated chemical opportunities they present for generating molecules of interest. The added value of the methodologies described, supported by mechanism schemes, as well as scopes of application, will be discussed. These developments will be organised as the main accessible chemical functions and sorted according to their type of MCR (3, 4 or 5-MCR).
