Abstract: A highly efficient oxidative C2-aroyloxylation of D-glucal with aromatic carboxylic acids has been achieved for the first time using 5 mol% Pd(OAc)2 and 1 equiv of PhI(OAc)2 to produce C2-aroyloxyglycals in good yields. The use of… read more here.

Abstract: Herein we reported a Mn(OAc)3·2H2O promoted radical sulfonation from functionalized alkenes and potassium metabisulfite (K2S2O5). The reaction realized the construction of oxindole, quinolinone, isoquinoline-1,3-dione, or benzoxazine structural fragments and the introduction of sulfonic moieties in… read more here.
