  Studies on the mechanism of mitomycin C(1) electrophilic transformations: structure-reactivity relationships

  摘要：

  Previous studies have demonstrated that reductive activation of mitomycin C (1) under acidic conditions furnished high yields of the C(1) electrophilic product 2,7-diaminomitosene (5). This adduct was also the major metabolite produced upon administration of 1 to HT-29 cytosol, purified HT-29 colon carcinoma cells, and rat hepatic DT-diaphorase. Proton capture at C(1) in 1 is known to proceed with high stereoselectivity. Information concerning the mechanism and the controlling factors that govern this transformation have been determined by examining the structure-reactivity relationship for mitomycin C (1), 10-decarbamoylmitomycin C (10), N(1a)-methyl-10-decarbamoyl-10-acetoxymitomycin C (11), mitomycin D (12), 10-decarbamoylmitomycin D (13), 7-aminoaziridinomitosene (14), N(1a)-(methanesulfonyl)mitomycin C (15), and N(1a)-(toluenesulfonyl)mitomycin C (16). The combined results obtained were consistent with the hypothesis that mitomycin C C(1) electrophilic reactions funneled through quinone methide 4. The high stereoselectivity of this process has been attributed (in part) to the protonated C(2) amino group in 4. In this scenario, proton capture occurred preferentially from the site opposite to the C(2) ammonium group in order to minimize adverse coulombic interactions.
