โฆ Synopsis
Civetone is a naturally occurring unique symmetric 17 membered cyclic ketone with the cis double bond. Few synthetic studies for civetone have been attempted. l-5 Stall prepared cis-civetone by separating the cis and trans-mixture. 1 One

Jasmonoids have been synthesized by the application of new synthetic methods. l,2) We now wish to report simple syntheses of methyl dihydrojasmonate and dihydrojasmone from a butadiene telomer by applying a palladium catalyzed reaction and [3,3]sigmatropic rearrangement in key steps. As a suitable s
Pellitorine is an insecticidal compound isolated from Anacyckus pyrethrum roots. Its structure was determinded as N-isobutyl-E,E-2,4\_decadieneamide (IVc), which was prepared easily from E,E-2,4-decadienoic acid, 1 and hence the preparation of the acid means the synthesis of pellitorine.

Reaction of 1,7-octadien-3-one with dimethyl malonate, followed by the reduction of the ketone produced dimethyl (3-hydroxy-7-octenyl)malonate, which was converted to 9-decen-5-olide after hydrolysis and decarboxylation. Reaction
