An efficient organocatalytic oxidation of racemic secondary alcohols, mediated by sodium hypochlorite (NaOCl) and 2-azaadamantane N-oxyl (AZADO), has been conveniently coupled with a highly stereoselective bioreduction of the intermediate ketone, catalyzed by ketoreductases, in aqueous medium. The potential of this one-pot two-step deracemization process has been proven by a large set of structurally different secondary alcohols. Reactions were carried out up to 100 mm final concentration enabling the preparation of enantiopure alcohols with very high isolated yields (up to 98 %). When the protocol was applied to the stereoisomeric rac/meso mixture of diols, these were obtained with very high enantiomeric excesses and diastereomeric ratios (95 % yield, >99 % ee, >99: 1 dr).

A new series of square-planar PdII-mediated foldamers with mononuclear and dinuclear helix or (double) hairpin structures were constructed by novel backbonecoordinative oxime peptides. Some of these metallo-foldamers allow significant structura

On the contrary: Utilizing the [Pd-(quinox)]-TBHP catalyst system, protected allylic amines were oxidized with high selectivity for the methyl ketone product. This is contrary to the results obtained by the substrate-controlled Tsuji-Wacker oxidation, which highlights the catalyst-controlled system presented here (see scheme). A variety of N-pro-tecting groups undergo selective oxidation with high ketone selectivity. TBHP = tert-butylhydroperoxide.
Reductive aldol and mannich-type reactions of azetidin-3-ones promoted by titanium tetraiodide

Based on anti-viral screening of our heteroaromatics derived from thalidomide, the γ-carboline skeleton has been identified as a superior scaffold structure for compounds with potent anti-bovine viral diarrhea virus (BVDV) activity. Structural development studies led to a potent anti-viral agent, SK5M (5-methyl-γ-carboline), with the EC50 of 0.26 μM.
