Treatment of 2,3-epoxy alcohols with tetramethylammonium triacetoxyborohydride afforded the ring-opening products at the C-3 position, regioselectively, where the presence of Me4NBH(OAc)(3) increased the reaction rate and regioselectivity by forming the chelation intermediate between the metal center and the epoxy alcohol oxygens.
