Palladium(II)-catalyzed intramolecular 1,2-additions to allenes substituted with an internal nucleophile have been developed. Carboxylic acids, alcohols, N-substituted amides, and carbamates were used as internal nucleophiles in the palladium-catalyzed re

Starting from cyclopentadiene (2) and 2-butynoic acid (3), and via the acids 5 and 7, the allyl alcohol 9 has been prepared. 9 reacts with the dienol ether 10 to give β-santalenone 11.Reduction of 11 with LiAlH4/AlCl3 yields, depending on the reaction temperature various amounts of hydrocarbons 25, 26, and β-santalenone (1), of the ketone 27 and of the alcohol 28.With NaBH4 the alcohols 28 and 29 have been obtained.
