Synthesis of Chiral Methyl Cucurbate and Its Analogs

Natural (+)-(1R,2S,3S)-methyl cucurbate (1b) and the (-)-δ-lactone of 3-epi-cucurbic acid (16) were synthesized from (+)-(1R,6S,7R)-bicyclonon-3-en-7-ol (5).Asymmetric hydrolysis of the acetate (8) of (+/-)-5 with pancreatin gave optically pure the

An Efficient and Stereocontrolled Synthesis of (+/-)-Methyl Epijasmonate and (+/-)-Cucurbic Acid

The total synthesis of epijasmonoids, (+/-)-methyl epijasmonate and (+/-)-cucurbic acid, starting from norbornene was described, where a key intermediate, 5β-hydroxy-2β-methoxycarbonylmethylcyclopentane 1β-acetic acid γ-lactone was efficiently prepared via a highly regioselective Baeyer-Villiger oxidation of 7-syn-substituted norbornanone based on remote substituent control.

Synthesis of (+/-)-Methyl Epijasmonate and (+/-)-Methyl Cucurbate

A novel synthesis of (+/-)-methyl epijasomonate (2) and the first synthesis of (+/-)-methyl cucurbate (4) were achieved startig from 2-allocyclohexane-1,3-dione (8).The synthetic epimer 2 had a stronger jasmin flavor than the trans-isomer 1 with 95percent purity.

An Efficient Total Synthesis of (+/-)-Methyl Jasmonate

A short synthesis of Methyl dl-Jasmonate from bicyclo nona-3,8-diene is described.
