An oxidative cleavage of alkyl C-Pd bond by H2O2 enables a palladium-catalyzed intramolecular aminohydroxylation to give various heterocycles with good yields and excellent diastereoselectivities. Facile transformation of these products provided a powerful tool toward the synthesis of 2-amino-1,3-diols and 3-ol amino acids. Preliminary mechanistic studies revealed that a SN2 type attack of water at a high-valent Pd center is involved.
