Abstract
The invention relates to a process for the grafting a chain on to the 10-position carbon atom of a tricyclene skeleton, more particularly for producing 10-substituted stereospecific tricyclenes, especially cis-.alpha.-santalene and cis-.alpha.-santalol. The process involves the production of a sulphone of the tricyclene, the reaction of the sulphone with the halogenated derivative of the desired side chain and desulphonating the product.
