Synthesis of 2-Trifluoromethyl-2,3,4,5-tetrahydro-1H-3-benzazepine Derivatives
摘要:
2-Trifluoromethyl-3-benzazepines (6 and 8) were efficiently prepared from 1,2,3,4-tetrahydro-1 -hydroxymethylisoquinoline (3) via ring expansion, utilizing a ring closure/ring opening strategy. Introduction of the trifluoromethyl group at 2-position in 7,8-dihydroxy-3-benzazepine (9) resulted in showing no affinity to dopamine D-1 and D-2 receptors.
