Abstract

A series of 4,5-bis-(alkyn-1-yl)imidazoles-'imidazole-fused' enediynes-were synthesized and their reactivities in photoinduced Bergman cycloaromatization reactions were determined. The more conformationally rigid analogues gave cycloaromatized products in good yields upon irradiation (450 W low-pressure mercury lamp, ambient temperature). A bicyclic analogue (3) was shown to cleave supercoiled plasmid DNA.
