The unchlorinated precursor 4 of CGA 80000 (1) was synthesized enantioselectively by two conceptionally different routes: a) by a 'chiral pool' approach starting from L-malic acid and b) by enantioselective hydrogenation of an enamide intermediate, catalyzed by chiral Rh- or Ru-phosphine-complexes.
