Several rearrangements of 17-mesyloxy and 12,17-dimesyloxy derivatives of ent-beyer-15-enes were carried out. Rearrangement processes mainly occurred with the participation of the functional group at C-12, although the group at C-17 and the C-15/C-16 double bond aided in an observed 16(13) → 12/11(12) → 13 double rearrangement. The influence of the groups at C-12 and their stereochemistry, of the mesyloxy
