Stereochemistry of an Ene Reaction involving 1,7-Dienes; Bicyclononanes from (3-Cyclohexenyl)diallylcarbinols

(3-Cyclohexenyl)diallylcarbinols undergo a thermal retro-ene reaction to give crotonylcyclohexenes at ca. 200 degC.A side-reaction is an ene reaction to give bicyclononanes.These become the main products above 300 degC.The stereochemistry of 2-allyl-1,4,6-trimethylbicyclo-6-nonen-2-ols and related compounds is discussed, and a case is described in which the allyl group is not freely rotating.

Alicyclic unsaturated compounds, their preparation and use of same as perfume ingredients

New alicyclic unsaturated compounds useful as perfume ingredients and perfume compositions containing same. The new compounds have formula STR1 possessing a methyl group attached to the carbon atom at position 3 or 4 of the ring and one double bond in one of the positions of the carbonyl side chain as indicated by the dotted line. Process for their preparation from new hydroxy compounds of formula STR2
