Article abstract of DOI:10.1007/BF00575039

The catalytic rearrangement of 20(S),24(R)-epoxydammarane-3,12β,25-triol 3-mono and 3,12-di(α-D-glucose 1,2-orthoacetate)s leads to the formation of the corresponding 12-mono- and 12,25-diglucosides.The anomalous regioselectivity of the catalytic rearrang
