The hydration of α,β-unsaturated ketones with water proceeded efficiently in the presence of In(OTf)3 (20 mol%) in aqueous media to afford synthetically versatile β-hydroxyketones in moderate to good yields with good functional group compatibility. The method also can be extended to the hydroalkoxylation of α,β-unsaturated ketones with various alcohols for the efficient synthesis of β-alkoxyketones as well as tetrahydrofuran derivatives.

An efficient method was developed for the conjugate addition of water to various α,β-unsaturated ketones by using bismuth(III) chloride as a catalyst. The reactions proceeded smoothly in the presence of a catalytic amount of BiCl3 (20 mol%) in aqueous media to furnish a variety of synthetically useful β-hydroxyl ketones in moderate to good yields. Apart from water molecule, various alcohols could also be employed as nucleophiles to react with α,β-unsaturated ketones, leading to β-alkoxyl ketones in modest to high yields. In addition, the mild reaction conditions also entailed the conjugate addition reactions to proceed with the tolerance to a range of functional groups.
Purification and characterization of a (r)-1-phenyl-1, 3-propanediol- producing enzyme from trichosporon fermentans aj-5152 and enzymatic (r)-1-phenyl-1, 3-propanediol production

An (R)-1-phenyl-1, 3-propanediol-producing enzyme was purified from Trichosporon fermentans AJ-5152. It was NADPH-dependent and converted 3-hydroxy-1- phenylpropane-1-one (HPPO) to (R)-1-phenyl-1, 3-propanediol [(R)-PPD] with anti-Prelog's specificity. It
