  • Title: Regioselective and 1,2-cis-α-Stereoselective Glycosylation Utilizing Glycosyl-Acceptor-Derived Boronic Ester Catalyst.
    Author: Nakagawa A, Tanaka M, Hanamura S, Takahashi D, Toshima K.
    Journal: Angew Chem Int Ed Engl; 2015 Sep 07; 54(37):10935-9. PubMed ID: 26205146.
    Abstract:
    Regioselective and 1,2-cis-α-stereoselective glycosylations using 1α,2α-anhydro glycosyl donors and diol glycosyl acceptors in the presence of a glycosyl-acceptor-derived boronic ester catalyst. The reactions proceed smoothly to give the corresponding 1,2-cis-α-glycosides with high stereo- and regioselectivities in high yields without any further additives under mild reaction conditions. In addition, the present glycosylation method was successfully applied to the synthesis of an isoflavone glycoside.
