title: First total synthesis of the 7,3'-linked naphthylisoquinoline alkaloid ancistrocladidine.
abstract: [structure: see text] The first total synthesis of the rare 7,3'-linked naphthylisoquinoline alkaloid, ancistrocladidine, has been completed. The key feature of the synthesis is the formation of the extremely hindered biaryl linkage by Pinhey-Barton ortho-arylation of a naphthol with an aryllead triacetate. The biaryl aldehyde formed is elaborated in 10 steps to form a 1:1 mixture of ancistrocladidine and its atropisomer. Recrystallization of the mixture afforded ancistrocladidine, which was identical in all respects to the reported data.
