A new and well planned approach has been accomplished for the total synthesis of 20-Deethyltubifolidine, which is effective for biological properties and fascinating molecules. This product embodies the ABCDE-ring system associated with the indole alkaloids. The synthesis was accomplished in six steps and produced a 38% yield.
