NEW MATERIAL:The compound of formula I (R -R are H or lower alkyl; Y is H or lower acyl; m is 1 or 2; n is 0-2). EXAMPLE:1,1,3,3,6-Pentamethyl-2,3,3a,4,5,7a-hexahydro-1H-inden-2-yl acetate. USE:A perfumery component of a perfumery composition. It has woody note suggesting vetiver-like perfume or cedarwood-like perfume, and strong diffusibility and perfume-retainability, and harmonizes well with various other perfumery materials. PREPARATION:The compound of formula I wherein Y is COR can be prepared by reacting a dienol ester of formula I [R is same as R -R ; A is group of formula II (Z is halogen or lower acyloxy) or group of formula III] in the presence of a zero-valent palladium complex and if necessary an alkali metal salt of a lower aliphatic manocarboxylic under heating. Hydrolysis of the product gives another compound of formula I wherein Y is H.
