摘要：

Both tri- and tetra(ethylene glycol) linked bis-chromium carbene complexes have been synthesized. These carbene complexes were photolyzed with N-protected imidazolines to give protected azapenams. These were transformed into polyether-linked basket dioxacyclams 4a,b and bis-dioxocyclams 5a,b. These compounds have-cavities for the complexation of both "hard" and "soft" metal ions.;The complexes of Ni, Ba, and Gd were synthesized.
