The palladium-catalyzed alkoxycarbonylation of allyl carbonates and allyl chlorides derivatives from terpenic olefins was carried out under atmospheric pressure of carbon monoxide and at moderate temperature. The reaction offers a very good method for the preparation of new beta, gamma -unsaturated esters and thus to provide a useful entry to new fuctionalized terpenic olefin products. The retention of optical activity of the synthesized products when the reaction is carried out from optically active substrates, has also been checked and discussed.
