Synthesis of a major mitomycin C DNA adduct via a triaminomitosene

We report here the synthesis of two amino precursors for the production of mitomycin C and 10-decarbamoylmitomycin C DNA adducts with opposite stereochemistry at C-1. The triamino mitosene precursors were synthesized in 5 steps from mitomycin C. In addition synthesis of the major mitomycin C-DNA adduct has been accomplished via coupling of a triaminomitosene with 2-fluoro-O⁶-(2-p-nitrophenylethyl)deoxyinosine followed by deprotection at the N² and O⁶ positions.
