“…Besides the shown examples with alkyne acceptors, alkenes were found to engage in cyanoesterification and cyanocarbamoylation reactions. For instance, Nishihara reported intermolecular palladium(II)-catalyzed cyanoesterifications of strained reactive alkenes 610 such as norbornene or norbornadiene (Scheme ). − Modification of the ester moiety of 609 with a variety of alkyl groups is tolerated and the functionalized norbornene derivatives 613 are obtained in moderate to high yields with high exo -selectivity. However, the process is limited to activated norbornenes and other less reactive olefin acceptors fail.…”
