Synthesis and antiangiogenic activity of exo -olefinated deoxoartemisinin derivatives
摘要:
10-exo-Bromoalkylidene and benzylidene deoxoarternisinin derivatives with antiangiogenic activity were synthesized from corresponding 10-alkanesulfonyl dihydroartemisinin and 10-phenylmethanesulfonyl dihydroartemisinin using a highly efficient, mild, and simple Ramberg-Backlund rearrangement.

Efficient Synthesis of exo-Olefinated Deoxoartemisinin Derivatives by Ramberg−Bäcklund Rearrangement
摘要:
10-exo-Bromoalkylidene- and benzylidenedeoxoartemisinins were synthesized from corresponding 10-alkane-sulfonyldihydroartemisinin and 10-phenylmethanesulfonyldihydroartemisinin using a highly efficient, mild, and simple Ramberg-Backlund rearrangement.
