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.
