Palladium-catalyzed alkoxycarbonylation of allyl phosphates proceeds with high efficiency affording the corresponding [3,y-unsaturatod esters stereoselectively with inversion of configuration at the allylic carbon center. Palladium complexes bearing chiral monodentate phosphine ligands are effective

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 โค, โฅ-unsaturated esters a
Synthesis of potential antiparisitic 5'-aminonucloesides such as 10 could not be accomplished using standard amination procedures. Palladium(0)-catalyzed amination of cyclic allylic acetates with benzylamine or phthalimide gave the corresponding protected amines. This method was then extended to the
