Syntheses of methyl jasmonate and analogues
Chapuis, Christian,Skuy, David,Richard, Claude-Alain
, p. 194 - 204 (2019)
This account corresponds to the presentation given by the main author on the occasion of the 2nd Swiss Industrial Symposium in Basel (October 19th, 2018). After a short historical introduction to methyl-jasmonate and methyl-epijasmonate, it essentially focuses on the reported more promising industrial approaches devoted to the synthesis of these naturally occurring odorants isolated from jasmine flowers. Some attempts to simplify these approaches, as well as independent unreported strategies are also presented. Several asymmetric methodologies are also discussed such as Xie hydrogenation, Corey-CBS reduction, enzymatic resolution, and 1,4-addition.

, p. 505 - 508 (1981)
Jesmonoids with cis-2-pentenyl side-chain such as cis-jasmone, methyl jasmonate, and jasmolone were easily synthesized from cis-4-heptenoic acid obtained by the ring opening reaction of β-propiolactone with di-cis-butenylcuprate.

Process for the preparation of chiral epoxides

, (2008/06/13)
The invention describes novel malonates and a process for using said malonates for the preparation of chiral epoxides of formula having a cyclanic (1R) configuration, the group in position 2 having a transconfiguration and the epoxy group having a cis-configuration with respect to the substituent in position 1 and wherein R is an alkyl group from C1to C4, linear or branched, and R1is an alkyl or an alkenyl group from C2to C8, linear or branched. The above process comprises the rearrangement of malonate (VII) to malonate (VI) and the decarboxylation reaction of into an ester of formula followed by the stereoselective epoxidation of the thus-obtained compound.
