Olefins play a vital role in the fields of bioscience, medicine, and chemistry. Stereo‐defined olefins are important resource in both chemical laboratory and industry. Using a palladium‐catalyzed decarboxylative transformation of vinyl cyclic carbonates, we have developed an efficient and reliable method for the direct construction of highly substituted olefins with the concomitant formation of a new Csp3‐Csp3 bond. The desired olefins could be generated in reasonable yields with good stereoselectivities, in contrast to the existing methods, which are usually non‐stereoselective. The palladium‐catalyzed decarboxylative transformation will undoubtedly provide new synthetic routes for the formation of multi‐substituted allylic scaffolds.
