  Abstract:

  Selective oxidation by bis[(trifluoroacetoxy)iodo]benzene (BTI)   provides an effective trap for quenching adducts formed   reversibly between dC and an ortho-quinone methide (QM)   under physiological conditions.  A model adduct generated by   4-methyl-o-QM and 2'-deoxycytidine is rapidly converted   by intramolecular cyclization and loss of aromaticity to a   characteristic product for quantifying QM alkylation.    However, BTI induces a surprising rearrangement driven by   overoxidation of a derivative lacking an alkyl substituent at the   4-position of the QM.
