The first asymmetric synthesis of benzophenanthridine dopamine D1 full agonist, dihydrexidine, was accomplished employing three key processes, external chiral ligand-cont rolled conjugate addition of phenyllithium, Curtius conversion of a carboxylic group to an amino group, and finally Pictet-Spengler type cyclization completing skeleton construction.
