Authors:Roman Kaiser  Dietmar Lamparsky
Abstract:Constituents of Osmanthus Absolute, Ist communication:2,5-Epoxy-megastigma-6,8-dienes Besides some further ionone derivatives we identified two new bicyclic oxacompounds ( 1a / 1b ) of the megastigmane type in the Osmanthus absolute. Isolation, special features of their spectral datas and synthesis starting from ethyl α-safranate are described. The synthetic pathway choosen allowed the additional identification of four substances occurring in the same natural substrate, because some synthetic by-products formed int he reaction sequence exhibited corresponding spectra and GLC. retention as the hitherto unknown components of the Osmanthus absolute.
