• An Efficient Diastereoselective Reduction of α-Alkyl-β-keto Carbonitriles with TiCl4/BH3 or LiBH4/CeCl3 to syn- or anti-α-Alkyl-β-hydroxy Carbonitriles

  alpha -Alkyl-beta -keto carbonitriles can be reduced stereoselectively to syn- and anti-alpha -alkyl-beta -hydroxy carbonitriles. The stereoselectivity can be explained in terms of properties of the Lewis acid employed. TiCl4 in noncoordinating solvents such as dichloromethane, followed by reduction with the borane/pyridine complex, predominantly led to the syrz-alpha -alkyl-beta -hydroxy carbonitriles, according to a chelate transition state, whereas CeCl3 in coordinating solvents such as THF, followed by reduction with LiBH4, predominantly led to the anti-isomers, in agreement with an open-chain transition state. The reduction to syn-alpha -alkyl-beta -hydroxy carbonitriles is the first general preparation of these compounds.

  The alkylation-reduction (AR) reaction of beta -keto nitriles by growing cells of Curvularia lunata CECT 2130 has been explored. The reaction conditions for the ethylation of benzoylacetonitrile have been optimized in terms of both yield and stereoselectivity and the mechanism of this biotransformation vas studied. The scope of this reaction has been extended to other alkylations (R = Et, Pr, Bu, iso-Bu) and to a series of aromatic and heteroaromatic substrates, yielding the corresponding optically active alpha -alkyl beta -hydroxy nitrites. The yield (directly related to competing carbonyl reduction reaction) depends on the substrate bulk. whereas the enantiomeric and diastereomeric excesses (both up to 98%) seem to be dependent on several Factors.

  Intermolecular oxycyanation of alkenes using p-toluenesulfonyl cyanide (TsCN) in the presence of tris(pentafluorophenyl)borane (B(C6F5)3) as a catalyst was shown to be feasible. The developed method offers a simple, scalable, and straightforward approach to access synthetically useful β-hydroxy nitrile derivatives.
