Oxygen-containing sulfur-rich compounds from the bark of the tropical garlic tree Scorodophloeus zenkeri Harms.
Two sulphoxides (2,3,5-trithiahexane 5-oxide and 2,4,5,7-tetrathiaoctane 2-oxide), three novel sulphones [S-(methylthiomethyl)methanesulfonothioate, methylthio(methylthio-methyl)sulfone, 2,3,5,7-tetrathiaoctane3,3-dioxide] and four known sulphones [methylsulphonylmethylthiomethane, methylmethanethiosulfonate, bis-methyl-sulphonylmethane, and bis-(methylthiomethyl)sulfone] were isolated from the bark extracts of Scorodophloeus zenkeri Harms. The structures were determined by spectral methods, essentially MS and NMR experiments.
