A NEW SYNTHETIC ENTRY TO PENTACYCLIC STRYCHNOS INDOLE ALKALOIDS

Cylization of the thionium ion generated by DMTSF treatment of dithioacetal 15 constitutes a new synthetic entry to the pentacyclic ring system of Strychnos indole alkaloids.

A New Synthetic Entry to Pentacyclic Strychnos Alkaloids. Total Synthesis of (+/-)-Tubifolidine, (+/-)-Tubifoline, and (+/-)-19,20-Dihydroakuammicine

A new strategy for the synthesis of pentacyclic Strychnos alkaloids has been developed.It consists in the closure of the five-membered E ring by cyclization upon the indole 3-position from a suitably N-substituted tetracyclic system embodying rings ABCD o
