chemoenzymatic Dynamic Kinetic Resolution (DKR) of unsymmetrical benzoins (Ar1≠Ar2) has been carried out, by using Pseudomonas stutzeri lipase stereorecognition pattern. After studying this lipase behaviour, a high preference towards acylation of those benzoins containing substituents in the phenyl ring rather than in the benzoyl moiety was observed. This fact allowed the development of the DKR process of this

metallophosphites as catalysts. As a result, nonenzymatic asymmetric cross silyl benzoin reactions have been achieved, giving optically active silyl ether-protected benzoin adducts. The reaction is general with respect to aryl, alkyl, and heterocyclic substrates with good to excellent yields and good to excellent enantioselectivities.

1-(4′-methylphenyl)-2-phenylethane diols with [1S:2R] and [1R:2S] absolute stereochemistry were synthesized and converted to the corresponding 4′-substituted [1S:2R] and [1R:2S] cis-stilbene oxides by the following sequence: formation of 2-methoxydioxalanes, conversion to halohydrins and cyclization to cis epoxides. Substantial amounts of opticallyactive 4′-substituted trans-stilbene oxides were also produced. The
