—— | 6-isopropoxy-2-(3'-isopropoxy-4'-methoxyphenyl)-5-methoxy-3-(3'',4'',5''-trimethoxyphenyl)benzofuran | 218903-30-1 | C31H36O8 | 536.622 |
The benzofuran (4), a ring-fused analogue of the potent antimitotic agent combretastatin A4 (1), has been prepared by a convergent route involving 5-endo-dig iodocyclization of o-hydroxytolan (5) as the key step. Compound (4), which has been characterized crystallographically as well as spectroscopically, is inactive as a tubulin-binding agent.
