• C1′ Acylated Derivatives of 2′-Deoxyuridine. Photolabile Precursors of 2′-Deoxyuridin-1′-yl
  作者：Marc M. Greenberg、Dong Jin Yoo、Brian K. Goodman

  DOI：10.1080/07328319708002519

  日期：1997.1

  C1' acylated derivatives of 2'-deoxyuridine (1a-c) were synthesized from 1-[3-deoxy-beta-D-psicofuranosyl]uracil (6). The acyl group is introduced via the C1' aldehyde (11). Following nucleophilic addition, the ketones (1a-c) are obtained via periodinane oxidation and desilylation with NH4F.
