Enzymic synthesis of chemically unstable cardiac glycosides by β-galactosidase from Aspergillus oryzae

Abstract β-Galactosidase obtained from Asp. oryzae was found to have strong transglycosylation activity. The glycosylation of water soluble and insoluble alcohols was successfully performed under such mild conditions at pH 5 at 4–37°C by using the enzyme.

Facile hydrogenation of aromatic nuclei with sodium borohydriderhodium chloride in hydroxylic solvents

Abstract Sodium borohydride-rhodium chloride in hydroxylic solvent was proved to be very useful for the reduction of aromatic nuclei to the corresponding saturated cycles under mild conditions.
