Syntheses and Crystal Structures of 4,5-Dihydro-2-(2′-hydroxyphenyl)oxazole-Containing Metal Complexes

The synthesis of the complexes 3 of various metals ligated to chiral 4,5-dihydro-2-(2′-oxidophenyl-?O)oxazoles-?N is described (Scheme). Three of them, i.e. 3a , 3e , and 3f containing Cu^II, Zn^II and Ni^II, respectively, were analyzed by X-ray diffraction studies. A series of Cu^II complexes ( 6a – d ) with differently substituted dihydrooxazoles have been synthesized.
