Fund Project: We are grateful to Professor Xiao Tian Liang, Institute of Materia Medi-caf Chirrese Academy of Medical Sciences, Beijing, for helpful discussion on the subject.

Treatment of denudatine 1 with 10％ HCl soln. at 30-40℃ for 1 day leads to another rearrangement product 3 along with a pair of epimers 2A and 2B. Upon adding a little EtOH in the reaction solution, only a pair of epimers 4A and 4B were obtained along with the unchanged starting material
