Naturally Occuring Terpene Derivatives, XLII. New Sesquiterpenes o the Genus OthonnaThe investigation of representatives from five sections of the genus Othonna shows that they are characterized by the presence of relatively strongly oxidized furanoeremophilanes. The constitution of 20 new members (1, 2, 6, 7, 9, 11, 12, 14, 16, 18, 28, 31, 34 and 37-43) has been established by means of their spectra as well as by chemical reactions. Besides these some sequiterpenes (24, 35, and 36) as well as a nor-compound (22) have been isolated and their structures elucidated. The close chemotaxonomical relationships to the neighbouring genera are discussed.
Notes:
Die Untersuchung von Vertretern aus fünf Sektionen der Gattung Othonna zeigt, daß hier relativ stark oxidierte Furanoeremophilane charakteristisch sind. Die Konstitutionen von 20 neuen Vertretern (1, 2, 6, 7, 9, 11, 12, 14, 16, 18, 28, 31, 34 und 37-43) werden durch ihre Spektren sowie durch chemische Reaktionen geklärt. Daneben werden einige Sequiterpene (24, 35, 36) sowie eine Nor-Verbindung (22) isoliert und ihrer Struktur geklärt. Die engen chemotaxonomischen Beziehungen zu den Nachbargattungen werden diskutiert.
