(2), (2S, 5E)-caryophyll-5-en-12-al (3), isospathulenol (4), (1R, 5R)- 1,5-epoxysalvial-4(14)-ene (5), and salvial-4(14)-en-l-one (6) have been identified for the first time in clary sage oil (Salviasclarea L.). The structures and absolute configurations of 1–6 are corroborated by partial syntheses and their organoleptic properties are discussed.
Reaction of the methylsulphonium salts of mintsulphide (1) and isomintsulphide (2) with methyl-lithium gives the desulphurization products, via the biradical intermediates, and the [2,3]sigmatropic re-arrangement products.
