There are provided (asymmetric) complex catalysts comprising metalncomplexes and Lewis acids as components, the metal complex being of formulan(1):n nwherein R 1 , R 2 , R 3 , R 4 , R 5 , R 6 , R 7 and R 8 are the same or different and arenindependently hydrogen, halogen, alkyl or the like; one of R 9 and R 10 is hydrogennand the other is alkyl of 1 to 4 carbon atoms or the like; Q is a singlenbond or alkylene of 1 to 4 carbon atoms; M is a metal ion; and A is a balancingncounter ion or ligand; processes for the production of these complex catalysts;nprocesses for the production of (optically active) alcohol derivatives,ncharacterized in that cyclic ether compounds are reacted with phenol derivativesnin the presence of these complex catalysts; and further processes fornproducing (optically active) nitrogen-containing heterocyclic compounds bynreacting these alcohol derivatives with halogenated nitrogen-containing heterocyclicncompounds in the presence of a base. |
