Abstract
E.s.r. spectra detected when ·OH reacts with the aldopentoses xylose and ribose are attributed to pyranose ring radicals, formed in essentially unselective attack; in contrast, in the corresponding reactions of the model compound tetrahydrofurfuryl alcohol, as well as some isopropylidene derivatives of glucofuranose, the hydrogen atoms on the carbon atoms adjacent to oxygen in a furanose ring are activated towards abstraction. A similar activation, evidently stereoelectronic in origin, is also proposed to account for the enhanced reactivity of C(5′)–H in the furanose ring of sucrose, a finding which may have particular relevance to the mechanism of radiation damage in DNA.
