Alkaloids which possess the rare hasubanan skeleton have been found to occur only in Stephania species. The structural elucidation of the first hasubanan ester alkaloid, stephavanine (from 2. abyssinica), has recently been reported.' We report herein the isolation and structural elucidation of a new
## Abstract The synthesis of compound **12** which has a hexahydroβ1,5βmethanoazocino[4,3β__b__]indole structure for the synthesis of pentacyclic strychnos type alkaloids (tubifolin and tubifolidine) is described. Many new compounds **5β12** have also been synthesized.
