A newmethod for the synthesis of beta(3)-amino acids is presented. Phthalimide protected allylic amines are oxidized under Wacker conditions selectively to aldehydes using PdCl(2) and CuCl or Pd(MeCN)(2)Cl(NO(2)) and CuCl(2) as complementary catalyst systems. The aldehydes are produced in excellent yields and exhibit a large substrate scope. Beta-amino acids and alcohols are synthesized by oxidation
