1,3-Dicarbonyl compounds were oxidized by oxygen in the presence of 5%Pd/C in DMF using K2CO3 as a base at room temperature to provide α-hydroxylated compounds.

Studies on α-Hydroxylation of Ticyclic Carboxylates;

Asymmetric epoxidation of α,β-unsaturated aldehyde/ketone as well as olefin, and asymmetric α-hydroxylation of carbonyl compounds catalyzed by various types of organocatalysts are reviewed in this paper.

α-Hydroxy ketones are frequently involved in biologically important compounds and,therefore,the determination of the stereochemistry of these structural elements has attracted the attention in natural products chemistry.

Analysis of use of α-hydroxy acid in cosmetics;

Polydepsipeptides, the copolymers of α-hydroxy acids and α-amino acids,are the most important representative of biocompatible biodegradable polyesteramids.
