An efficient and broadly applicable method for the construction of functionalized electron rich 1,3‐dienes through a base promoted isomerization reaction of propargylic ethers is presented. This process features easy handling reaction conditions, transition‐metal‐free isomerization, high isolated yields, and most of all, it could be used for late stage modification of natural products.
