A palladium-catalyzed intramolecular aminohydroxylation of alkenes was developed, in which H2O2 was applied as the sole oxidant. A variety of related alkyl alcohols could be successfully obtained with good yields and excellent diastereoselectivities, which directly derived from oxidation cleavage of alkyl C-Pd bond by H2O2. 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 major nucleophilic attack of water (SN2 type) at high-valent Pd center contributes to the final C-O(H) bond formation.
Iodocyclization of the (Tolylsulfonyl)- and (Trichloroacetyl)carbamates of Secondary α-Allenic Alcohols. Highly Diastereoselective Synthesis of syn-1,2-Amino Alcohols and trans-5-Alkyl-1-oxo-2-oxazolidine-4-carboxylic Acids
