Two triterpenyl fatty acid esters were isolated from the chloroform soluble fraction of Fagonia cretica and their structures elucidated as 3β-12-ursen-3yl-docosanoate (1) and 3β-12-ursen-3yl-nonacosanoate (2) by 1D-NMR, 2D-NMR, mass spectrometric and chemical analyses. Both new compounds were also evaluated for their lipoxygenase inhibitory potential using Baicalein as a standard.

Phosphoranes, produced by treating alkyltriphenylphosphonium bromides with lithium hexamethyldisilazide, reacted with ω-oxo esters to give modest yields of the corresponding methyl cis-alkenoates.By an alternative method, treatment of ω-iodo esters with the complexes formed from reactions of alkylcopper(I) and Grignard reagents gave methyl alkanoates, cis-alkenoates, and methylene-interrupted cis,cis-alka-dienoates and cis,cis,cis-trienoates.The stereochemical integrity of the esters was determined by 13C NMR spectroscopy.
