Zusammenfassung:PCT No. PCT/EP97/06782 Sec. 371 Date Aug. 6, 1999 Sec. 102(e) Date Aug. 6, 1999 PCT Filed Dec. 4, 1997 PCT Pub. No. WO98/24741 PCT Pub. Date Jun. 11, 1998A process for the preparation of carbocyclic stereoisomers of formulae (I), (I'), (IIA'), (IIB'), (VA') and (VB'), including enantiomerically pure (IIA'), (I) and (I') utilizing fractional crystallization of salts formed with a chiral base; a reducing agent; a protecting group removing agent or a protecting group providing agent.
