## Abstract An efficient synthesis of methyl (±)‐jasmonate and (__Z__)‐jasmone is described. The Key step is a phase‐transfer reaction between cyclopentane (**9**) and 1, 4‐dibromo‐2‐pentene (**6a/b**) to give the spiro [2.4]hepten‐4‐ones **4a** and **4b**.
Considerable interest has recently been focused on the nucleophilic ringopening reaction of geminally activated cyclopropanes 2 and the reactions with thiols 3 or amines 4 were utilized as a crucial step for construction of complex molecules. In this paper, we wish to report the ring-opening reactio
