New polysulphanes from aerial parts of Ferula behboudiana Rech. f. & Esfand

Abstract

The chloroformic extract of the aerial parts of Ferula behboudiana (Umbelliferae) afforded four new polysulphane derivatives: 1-sec-butyl-2-[(E)-3-(methylthio)prop-1-enyl]disulphane (1), 1-sec-butyl-2-[(Z)-3-(methylthio)prop-1-enyl]disulphane (2), 1-[(E)-3-(methylthio)prop-1-enyl)-2-(1-(methylthio)propyl]disulphane (3) and 1-[(Z)-3-(methylthio)prop-1-enyl)-2-(1-(methylthio)propyl]disulphane (4). Structural elucidation of diastereomers was carried out easily due to completely resolved signals in ¹H NMR spectra and with 2D-NMR techniques.
