Methods of modifying polypyrrolic macrocycles by use of a 1,3-dipolar cycloaddition are described. The methods may be used to produce compounds for further derivatization to produce photosensitizing agents of interest....http://www.google.es/patents/US6620929?utm_source=gb-gplus-sharePatente US6620929 - 1,3-Dipolar cycloadditions to polypyrrolic macrocycles
