The first examples of catalysis of aliphatic C-H hydroxylation by an iminium salt are presented. The method allows the selective organocatalytic hydroxylation of unactivated 3° C-H bonds at room temperature using hydrogen peroxide as the terminal oxidant. Hydroxylation of an unactivated 2° C-H bond is also demonstrated. Furthermore, improved functional group compatibility over other catalytic methods is reported in the form of selectivity for aliphatic C-H hydroxylation over alcohol oxidation. On the basis of initial mechanistic studies, an oxaziridinium species is proposed as the active oxidant.
OXIDATION OF TETRAHYDROFURAN METHANOL DERIVATIVES WITH PYRIDINIUM CHLOROCHROMATE: A FACILE SYNTHESIS OF γ-BUTYROLACTONES

Treatment of a number of tetrahydrofuran methanol derivatives with pyridinium chlorochromate led to the formation of the corresponding γ-butyrolactones with the loss of one or more carbon atoms in good yields under mild reaction conditions.
