A convergent synthesis of a novel estrogen receptor-targeted drug hybrid was developed based on structures of the potent anti-proliferative mitomycin C and the steroidal anti-estrogen RU 39411. The steroidal antiestrogen was prepared with an azido-triethylene glycoloxy linker while the mitomycin C derivative (porfirimycin) incorporated a complementary 7-N-terminal alkyne. The two components were ligated using the Huisgen [3 + 2] cycloaddition ("click") reaction. Preliminary biological assays demonstrated that the final hybrid compound retained both potent anti-estrogenic and anti-proliferative activities.

9-epi-Mitomycin B (2b) with the same C-9 stereochemistry as mitomycin C(1) was synthesized from mitomycin B (2a) through inversion at the C-9 position. 10-O-Decarbamoylmitomycin D (8a), derived from 2a in two steps, was employed as the substrate for the epimerization.The 10-hydroxymethyl group in 8a was epimerized on treatment with diazabicycloundec-7-ene to afford 8b.Successive transformation performed on the functional groups of 8b gave the desired 2b in four steps.The stereochemistry in 2b was confirmed by conversion of 2b to the known mitomycin F (4).

The leuco form of mitomycin F reacts with silica gel in the presence of oxygen to afford 9-epimitomycin B.A notable stability is manifested by hydroquinoid forms (leucomitomycin) bearing a 9,10-exocyclic methylene group.
