  • Chiral building blocks of carbocyclic N- and C-ribonucleosides through biocatalytic asymmetrisation of meso-cyclopentane-1,3-dimethanols
    Mohar, Barbara ; Štimac, Anton ; Kobe, Jože, 1942-
    Enantiomerically pure chiral building blocks, lactone 1 in either enantiomericform and cyclopentanecarbonitriles 10 and 15, were prepared efficiently through lipase catalysed enantioselectivew ... hydrolysis of meso-diesters 5a-c or transesterification of their parent diol 2 with vinyl acetate in an organic solvent providing chiral monoesters 6a-c or ent-6a of >99% ee in the crucial step. The combined HLADH catalysed and chemical oxidation of 2 resulted in (-)-1 of 74% enantiomeric purity.
