摘要

A large-scale synthesis of a tricyclic D1/D5 dopamine antagonist based on regio- and stereoselective ring opening of an aziridinium ion with a Grignard reagent was optimized and scaled up. ... Sch 39166 (1) is a potent dopamine D-1 antagonist that was initially developed to treat schizophrenia. 1 Subsequent in vivo animal autoradiography studies 2 demonstrated that 1 was a highly selective D1/D5 antagonist. Since the neurotransmitter dopamine is involved in ...
