AN EFFICIENT SYNTHETIC METHOD OF METHYL (+/-)-JASMONATE

An efficient synthetic method of methyl (+/-)-jasmonate is described. 2-Pentynyl-2-cyclopentenone, the key intermediate in this route, was synthesized by applying the palladium-catalyzed enone formation from allyl β-keto carboxylate as a key reaction.
