Synthesis of the azocino[4,3-b]indole core structure for the synthesis of strychnos alkaloids

The synthesis of compound 12 which has a hexahydro-1,5-methanoazocino[4,3-b]indole structure for the synthesis of pentacyclic strychnos type alkaloids (tubifolin and tubifolidine) is described. Many new compounds 5-12 have also been synthesized.
