A series of 1,2,3-triazole-containing pyrrolo[2,1-c][1,4]benzodiazepine dimers have been prepared efficiently by employing a 'click' chemistry protocol. This method involves 1,3-dipolar cycloaddition of terminal alkynes with organic azides using a Cu(I)-catalyst. Further, these molecules exhibited i

β¦ Synopsis
Reaction of various ct-unsubstituted pyrrole derivatives with trimethyl(porphyrinylmethyl)ammonium iodides (generated in situ from the corresponding meso-dimethylaminomethylporphyrins and iodomethane) afforded a number of symmetrical and unsymmetrical porphyrinylmethylpyrrole adducts, including dimers linked by one and two pyrrolylmethylene units. The NMR spectra of the monopyrrolelinked dimers indicate a preference for a face-to-face conformation.
