β-Amino-carbonyl fragments are important structures of many bioactive molecules and pharmaceuticals and critical synthetic blocks which can be easily converted into other structures and compounds. A novel method for preparing β-amino-carbonyl compounds with oxygen as an oxidant, palladium acetate and cuprous chloride as catalysts was reported. The chiral high allyl amine compounds can be converted into corresponding β-amino carbonyl compounds with moderate to good yield, good substrate scope, and tolerance of chiral centers. Natural product（＋）-sedridine was synthesized with 32% yield.
