Abstract
Three structurally similar deoxynucleosides (thymidine, O4-ethylthymidine, and 2'-deoxyuridine) were studied by mass spectrometry as pentafluorobenzyl, cinnamyl, or mixed derivatives. The purpose of the work was to define the usefulness of such derivatives for structural elucidation of deoxynucleosides. The compounds were ionized in three ways: electron capture negative ion, positive ion chemical ionization, and electron impact. For each of the derivatives examined, the combined spectra were well suited for structural elucidation purposes.
