δ-Pyronene, a terpenic synthon recently made industrially available from myrcene, has been characterized. It is an excellent raw material for the preparation of numerous intermediates used in the synthesis of perfumes and retinoids. Furthermore, new terpenic compounds including the cyclogeranyl skeleton have been prepared.

Cyclic ketones and their use as perfuming ingredients

Novel compounds of formula STR1 wherein the dotted lines indicate the location of a single or double bond, symbol R1 stands for a hydrogen atom or a methyl radical, symbol R2 represents a linear or branched, saturated or unsaturated, C1 to C4 alkyl radical, provided that R1 is not hydrogen when R2 represents a methyl or n-propyl radical and the ring is saturated. Compounds (Ia) are useful as perfuming ingredients. A process for their preparation is disclosed.
