Graphical Abstract

Cut and paste: A novel metal-free allylic C−C bond cleavage of simple unfunctionalized olefins was developed for the synthesis of valuable cinnamyl aldehyde derivatives with high regio- and stereoselectivity. This method not only provides a new approach to cinnamyl aldehydes, but also expands the application of alkyl azides as well as the recombination of olefins in organic synthesis.

Abstract

A novel metal-free allylic C−C σ-bond cleavage of simple olefins to give valuable cinnamyl aldehydes is reported. 1,2-Aryl or alkyl migration through allylic C−C bond cleavage occurs in this transformation, which is assisted by an alkyl azide reagent. This method enables O-atom incorporation into simple unfunctionalized olefins to construct cinnamyl aldehydes. The reaction features simple hydrocarbon substrates, metal-free conditions, and high regio- and stereoselectivity.
