Norbornane derivatives having hydrocarbon side chains, the processes for preparing the same and perfume compositions containing the same. The norbomane derivatives are represented by the following general formula (I)
wherein C2 is an ethyl group, an ethylidene group or a vinyl group each connected to 5 or 6 position of the norbornane ring, each of R, and R2 is a hydrogen atom or a methyl group, and R3 is a formyl group or a group represented by the following general formula (II)
wherein R4 is a methyl group, an ethyl group, a n-propyl group or an isopropyl group, and X is a carbon atom of the norbomane ring. The above norbornane derivatives give a wide variety of woody fragrances and are useful as components for various perfume products.
