Abstract

A novel and succinct method for the synthesis of N-cyanomethyl amides from allylic alcohols with AIBN as the nitrile source is developed. Owing to the coordination effect with the copper catalyst, a ketenimine intermediate is formed via couplings of isobutyronitrile radicals. The copper-activated ketenimine could subsequently be intercepted by allylic alcohols and undergo Claisen rearrangement to furnish N-cyanomethyl amides. Further functional group transformations of the N-cyanomethyl amide products are also described.
