|Title:||Detection, synthesis and absolute configuration of (+)-nortaylorione, a new terpene from Artemisia annua|
|Abstract:||Nortaylorione a new nor-sesquiterpene, was identified among minor components of Artemisia annua (hybrid plants) essential oil. Its relative and absolute configurations were determined by GC and GC/MS equipped with a chiral column and coinjecting the essential oil with synthetic standards (racemic and homochiral), obtained in a few steps from commercial reagents. Pauson-Khand reaction was used as the key reaction in both synthetic pathways. The new natural product, named (+)-nortaylorione, is the (1'S)-cis-2-[2',2'-dimethyI-3'-(3 ''-butanon-l ''-yl)-cyclopropyl]2-cyclopenten-1-one. (C) 1997 Elsevier Science Ltd.|
