An atom-economical transition-metal-free protocol for the stereoselective synthesis of conjugated trienes has been developed via base promoted C-C sigma-bond cleavage reactions of allyl carbonyl compounds. This methodology efficiently constructs a broad range of conjugated trienes with the advantages of mild reaction conditions, low cost, and operational simplicity.
