There are provided (asymmetric) complex catalysts comprising metal complexes and Lewis acids as components, the metal complex being of formula (1): <CHEM> wherein R<1>, R<2>, R<3>, R<4>, R<5>, R<6>, R<7> and R<8> are the same or different and are independently hydrogen, halogen, alkyl or the like; one of R<9> and R<10> is hydrogen and the other is alkyl of 1 to 4 carbon atoms or the like; Q is a single bond or alkylene of 1 to 4 carbon atoms; M is a metal ion; and A is a balancing counter ion or ligand; processes for the production of these complex catalysts; processes for the production of (optically active) alcohol derivatives, characterized in that cyclic ether compounds are reacted with phenol derivatives in the presence of these complex catalysts; and further processes for producing (optically active) nitrogen-containing heterocyclic compounds by reacting these alcohol derivatives with halogenated nitrogen-containing heterocyclic compounds in the presence of a base. |
