AN EFFICIENT SYNTHETIC METHOD OF METHYL (+/-)-JASMONATE
Kataoka, Hideaki,Yamada, Toshiro,Goto, Kuniaki,Tsuji, Jiro
, p. 4107 - 4112 (1987)
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.
