9-Octadecen-18-olide

Two approaches to the formation of large rings by metathesis have been attempted. The first approach is demonstrated by the synthesis of 9-octadecen-18-olide by Tsuji by the closure of an a,(o-diene... [Pg.1118]

JR,9Z)-9-Octadecen-4-olide (30) is the female pheromone of the currant stem girdler (currant sawfly, Janus integer). Both the enantiomers of 30 were synthesized as summarized in Scheme 44 [69]. Lipase-catalyzed asymmetric acetylation of ( )-A was the key-step to give unreacted CR)-A and acetylated (S)-B. [Pg.30]

A lactone, (2 )-9-octadecen-4-olide, has been identified as a female specific antennally active compound from the currant stem girdler, Janus integer Norton (Hymenoptera Cephidae). Comparison of the y-lactone and a synthesized racemic mixture of (2 )-9-octadecen-4-olide on a chiral GC column showed the presence of a single component in the natural material. ... [Pg.295]
