CHEMISTRY OF DENUDATINE V.1 REARRANGEMENT REACTIONIR OF DENUDATINE.
HETEROCYCLES, Vol. 45, No.4, 1997, 659～672，-0001，（）：
Treatment ofdenudatine 1 with 10% HCI solution at 30-50C leads to rearrangement to two pairs of epimers (5A) and (SB), (8A) and (8B) as well as 7 and 15. The rearrangement mechanisms are discussed. Conversion of 7→5A/5B→15 under acid catalysis can be realized. While the conversion of 15 to 5A/5B can be realized with NaOH-DMF at 120-126 C. Structures for 5A/5B, 7, 8A/8B and 15 were established on the basis of chemical and spectral methods.
