Synthesis of (+/-)-10,22-Dioxokopsane and (+/-)-Kopsanone, Heptacyclic Indole Alkaloids. Synthetic and Mechanistic Studies

The total synthesis of the heptacyclic indole alkaloids (+/-)-10,22-dioxokopsane (2) and (+/-)-kopsanone (3, X=O) is described.The imine 20 was condensed with β,β,β-trichloroethyl chloroformate to give the tetracyclic carbamate 21.Removal of the carbamate
