This invention describes various processes for synthesis and resolution of
racemic amino-substituted fused bicyclic ring systems. One process
utilizes selective hydrogenation of an amino-substituted fused bicyclic
aromatic ring system. An alternative process prepares the racemic
amino-substituted fused bicyclic ring system via nitrosation. In
addition, the present invention describes the enzymatic resolution of a
racemic mixture to produce the (R)- and (S)-forms of amino-substituted
fused bicyclic rings as well as a racemization process to recycle the
unpreferred enantioner. Further provided by this invention is an
asymmetric synthesis of the (R)- or (S)-enantiomer of primary
amino-substituted fused bicyclic ring systems.
