The reaction of 4, 6-O-benzylidene-d-pyranosides with a stoichiometric amount of TsCl, AcCl, and BzCl in the presence of silver(I) oxide and a catalytic amount of potassium iodide led to monosubstituted derivatives in high regioselectivity and in good yields.
的4反应,6- ö -benzylidene- d -pyranosides用的TsCl,ACCL,和BzCl的在银存在的化学计量量(I),氧化,并导致高的区域选择性和在单取代的衍生物碘化钾催化量良品率高。
