, p. 475 - 476 (1986)
ψ-Lactones were easily prepared from the direct reaction of methyl β-bromopropionate with ketones mediated by lanthanoid metals; a lanthanoid metal ester homoenolate (β-lanthanoid metal substituted ester) is postulated as a reaction intermediate.

Oxygenation of Tetrahydrofurans with Combined Use of Molecular Oxygen and α-Diketone Catalyzed by Cobalt(III) Complex
Hata, Eiichiro,Takai, Toshihiro,Mukaiyama, Teruaki
, p. 1513 - 1516 (1993)
In the presence of catalytic amount of cobalt(III) complex such as tris(acetylacetonato)cobalt(III), tetrahydrofurans are oxygenated into the corresponding γ-butyrolactones under mild conditions on treatment with an atmospheric pressure of molecular oxygen and α-diketones having hydrogen atom next to the carbonyl carbon.

Paragraph 0018; 0030-0037, (2020/07/13)
The synthetic method comprises the following steps: 2 - octanol serving as a solvent and di-tert-butyl peroxide as an initiator, and refluxing to separate t-butyl alcohol and water, vacuum distillation to obtain 2 - octyl 2 - (3H) furanone, and then dehydrating and dehydrating 5 - methyl -5 - hexyl -2 -2 -5 - (3H) furanone molecules under the action of a solid acid catalyst to recover the dihydrojasmonic spice product after the reflux reaction is carried out 5 . The synthesis method provided by the invention has the advantages of relatively simple steps, no acid waste water generation and high total yield, and moreover, the content of the product and the dihydrojasmonone synthesized through the synthetic method provided by the invention is higher than 98% and above.
