Palladium‐Catalyzed Carbonylative Multicomponent Fluoroalkylation of 1,3‐Enynes: Concise Construction of Diverse Cyclic Compounds.

Multicomponent reactions, particularly those entailing four or more reagents, have presented a longstanding challenge due to the inherent complexities associated with balancing reactivity, selectivity, and compatibility. In this study, we describe a palladium‐catalyzed multi‐component fluoroalkylative carbonylation of 1,3‐enynes. A series of products featuring three active functional groups‐allene, fluoroalkyl, and carboxyl, were efficiently and selectively integrated in a single chemical operation. Furthermore, more intricate fluoroalkyl‐substituted pyrimidinones can be constructed by simply altering the 1,3‐bisnucleophilic reagent. This approach also provides a valuable strategy for the late‐stage modification of naturally occurring molecules and concise construction of diverse cyclic compounds. [ABSTRACT FROM AUTHOR]
