Application of a palladium-catalyzed coupling between 3 and 5a to the synthesis of the novel 5-HT1DreceptoragonistMK-0462 (1), a potential anti-migraine drug, is described.
Synthesis of new iboga-analogues, replacing the indole ring with a benzofuran moiety has been described. Starting materials are the suitably substituted benzofuran derivatives and have been synthesized by Pd-catalyzed reactions. The conversion of endo-6-methylcarboxylate substituted dehydroisoquinuclidine to exo-isomer, a key component of iboga-alkaloids has been achieved in the presence of NaOMe in
