Abstract
Disclosed are a polyene compound, preparation method and use thereof. Provided in the present invention is the preparation method of a polyene compound I, comprising the following steps: under an action of a base and in an organic solvent, conducting a Witting reaction on a compound II and a compound III to obtain the polyene compound I. By the preparation method in the present invention, a coupling reaction results in good product purity without producing an obvious by-product and involves no heavy metal, thus facilitating a control over product quality and costs, having a simple operation and mild reaction condition, enabling high reaction conversion, a high yield, few by-products, high resultant product purity, low production costs and simple post-processing, and being suitable for industrial production.
