The “most unusuall of all the isoquinoline alkaloids,” the title compound 2 , is characterized by a biphenyl system configurationally stable to above 200°C. The key step in the synthesis is intramolecular CC bond formation in the intermediate 1 , in which the two molecular halves are joined by means of lactone formation.
