  • Intermediates to 4-amino- hexahydrobenz (cd) indoles and processes therefor
    Patent number: 5559245
    Abstract: New intermediates, and processes therefor, provide an efficient method for deriving 4-amino-1,2,2a,3,4,5-hexahydrobenz[cd]indoles, which are themselves intermediates to useful CNS agents, from the Kornfeld-Woodward ketone and like compounds. Preferred embodiments provide means for the preparation of substantially pure enantiomers of the desired 4-amino-1,2,2a,3,4,5-hexahydrobenz[cd]indole.
    Type: Grant
    Filed: September 12, 1995
    Date of Patent: September 24, 1996
    Assignee: Eli Lilly and Company
