Preparation method of echinenone

The invention discloses a preparation method of echinenone. According to the method, beta-apo-12 '-carotenal is oxidized into 4-oxo-beta-apo-12'-carotenal through regioselective oxidation, and then aC15 fragment is connected through a Witting reaction, so that the echinenone can be synthesized through a short-circuit line under the conditions of mild reaction conditions and simple process operation. The method has the advantages of short synthetic route, considerable product purity and yield, easily available raw materials, low cost, better industrial value, easiness in operation in the production process, no generation of toxic and harmful intermediates, and accordance with the concept of green and environment-friendly chemistry.
