Abstract

A diastereoselective synthesis of 1,2,3,4,4a,14a-hexahydro-8aH-xantheno[9,8a-b]indole and 3,4b,5,6,7,8,8a,15b-octahydro-4H-benzo[d]naphtho[1,8-ab]carbazole-4-one derivatives has been developed based on a domino sequence that involves electrophilic ortho-spirodearomatization via the Ritter reaction and intramolecular nucleophilic trapping of spiro-σ-intermediates.
