    Chemoenzymatic Asymmetric Synthesis of Pregabalin Precursors via Asymmetric Bioreduction of β-Cyanoacrylate Esters Using Ene-Reductases
    摘要:
    The asymmetric bioreduction of a library of beta-cyanoacrylate esters using ene-reductases was studied with the aim to provide a biocatalytic route to precursors for GABA analogues, such as pregabalin. The stereochemical outcome could be controlled by substrate-engineering through size-variation of the ester moiety and by employing stereochemically pure (E)- or (Z)-isomers, which allowed to access both enantiomers of each product in up to quantitative conversion in enantiomerically pure form. In addition, stereoselectivities and conversions could be improved by mutant variants of OPR1, and the utility of the system was demonstrated by preparative-scale applications.

  • Stereocontrolled Synthesis of the cis-Hydroxydecalin System: Towards Biologically Active 19-nor-Clerodanes
    作者:Paul Malek Mirzayans、Rebecca H. Pouwer、Craig M. Williams、Paul V. Bernhardt
    DOI:10.1002/ejoc.201101807
    日期:2012.3
    The 19-nor-clerodanes are compact, densely functionalized diterpenes based on a stereocentre-rich decalin scaffold. To date only a few examples of the 19-nor-clerodanes have been synthesized, hence new flexible strategies are required. We herein describe the stereocontrolled construction of the cis-hydroxy decalin core in a concise fashion.

    Palladium catalyzed cross coupling reactions of (arylvinyl)tributyl stannanes with vinyl triflates resulted in the production of stereochemically pure trisubstituted E- and Z-olefins in very good yields. These olefins were transformed to the corresponding all-E- and 9Z-heteroaryl-retinoic acid analogs via Horner-Emmons reaction and subsequent basic hydrolysis in excellent yields.
