    • This invention relates to processes for the synthesis of various optically active amino pyrrolidinyl stereoisomers, or enantiomers, that may be attached to quinolonecarboxylic acids or naphthyridones. Processes and essential intermediates are disclosed and claimed for the synthesis of compounds represented by the structure shown in figure BG4-1, where R , R and R are defined independently and are H, --(C1-C8)alkyl, --(C3-C8)cycloalkyl, --(C1-C8)alkyl-(C3-C8)cycloalkyl, --(C6-C12 aryl), --(C1-C8)alkyl-(C6-C12 aryl), or the aryl or alkyl is substituted with one to three of the following groups, (C6-C12 aryl), (C1-C3)alkyl, (C1-C3)alkoxy, halogen, trifluoromethyl; where R is --(C1-C8)alkyl, --(C3-C8)cycloalkyl, --(C1-C8)alkyl-(C3-C8)cycloalkyl, --(C6-C12 aryl), --(C1-C8)alkyl-(C6-C12 aryl), or the aryl or alkyl is substituted with one to three of the following groups, --(C6-C12 aryl), --(C1-C3)alkyl, --(C1-C3)alkoxy, halogen, trifluoromethyl; depending upon the starting materials used, compounds represented by the structure shown by figure BG4-1 may have one of either of the two stereochemical arrangements shown, or, if the starting materials are a racemic mixture, the reaction may produce a 1:1 ratio of the combination of products shown in figure BG4-1, i.e. a racemic mixture.
