Abstract
α-Cyano aldehydes undergo selective transition-metal-catalyzed allylation to provide α-allylated nitriles. The transformation leads to linear allylated nitriles with palladium catalysts whereas an iridium catalyst provides branched substitution products. TBD-catalyzed retro-Claisen cleavage is leveraged to attain selective monoallylation.
