Total Synthesis of the Benzo[c]phenanthridine Alkaloids, Terihanine and Isoterihanine, and Their Antitumor Activity
摘要:
A new total synthesis of terihanine (2a) and isoterihanine (2b) was established by our new bond formation between the C4b and N5 positions of the benzo[c]phenanthridine ring based on a microwave-assisted thermal electrocyclic reaction of 2-cycloalkenylbenzaldoxime as an aza 6 pi-electron system. In addition, the antitumor activity of these synthesized compounds, including nitidine and nornitidine was evaluated in HCT-116 cells.
