G. Karagianis et al., PREPARATION AND CHARACTERIZATION OF PORPHYRIN-C ANALOGS AS AGENTS FORPHOTODYNAMIC THERAPY, Australian Journal of Chemistry, 46(11), 1993, pp. 1755-1762
The porphyrin c analogues (4)-(10) were prepared by reaction of the ap
propriate thiol with the dibromohematoporphyrin adduct (3). The porphy
rins were obtained in high yield and purity and were characterized by
H-1 and C-13 n.m.r. spectroscopy and f.a.b. mass spectrometry.
