An enantiospecific synthesis of (+)-methyl epijasmonate and (-)-methyl cucurbate from L-glutamic acid

An enantiospecific route to jasmonoid natural products, (+) - methyl epijasmonate and (-) -methyl cucurbate from L-glutamic acid is reported. The key step is a 5-(3,4) ene cyclization of a functionalized 1,6-diene as chiron, which sets up three chiral centres with a high degree of diastereoselectivity.

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.
