The first asymmetric synthesis of a dopamine D1 agonist, dihydrexidine, employing asymmetric conjugate addition technology

The first asymmetric synthesis of benzophenanthridine dopamine D1 full agonist, dihydrexidine, was accomplished employing three key processes, external chiral ligand-controlled conjugate addition of phenyllithium, Curtius conversion of a carboxylic group

Improved asymmetric synthesis of dopamine D1 full agonist, dihydrexidine, employing chiral ligand-controlled asymmetric conjugate addition of aryllithium to a nitroalkene

Asymmetric conjugate addition of 2-trityloxymethylpheyllithium to a nitroalkene was mediated by a chiral ligand to give the key intermediate for dopamine D1 full agonist dihydrexidine 1. The shortcut of both Curtius rearrangement and Pictet-Spengler type
