Title: Chemical composition of fragrant materials. Synthesis and distribution of (-)-mintsulfide,a novel sulfur-containing sesquiterpene.
Abstract: (-)-Mintsulfide [(-)-1], a new sulfur-containing sesquiterpene found in peppermint oil, was synthesized from (-)-germacrene-D[(-)-3] by a photochemical reaction and was confirmed to be (1R)-cis-2, 6-epithio-cis-8-isopropyl-1-methyl-5-methylene-cis-bicyclo-[5, 3, 0]-decane. The existence of 1 was confirmed in 13 of 74 essential oils analyzed.
