A three-stage method has been developed for the stereoselective synthesis of (±)-cis-tetradec-5-en-4-olide — the racemate of the sex pheromone of the Japanese beetlePopillia japonica C. The key reactions used were the stereoselective cis reduction of a triple bond with the aid of heterogeneous hydrogenation catalysts (zinc-copper couple, nickel boride,(More)
The comparative oxidation of trans-hex-2-enol to leaf aldehyde has been effected with the aid of manganese dioxide, chromium oxide, and sodium dichromate in DMSO. It has been established that sodium dichromate in DMSO gives the best yield (not less than 80%) and a product of higher purity. It is a comparatively new reagent in organic synthesis. The use of(More)
In a study of the components of theMatricaria discoidea DC. growing in Estonia, three individual compounds have been isolated from the essential oil. On the basis of spectral characteristics, their structures have been shown as geranyl isovalerate, trans-β-farnesene, and herniarin.
