Uracil- and thymine-substituted thymidine and uridine derivatives

Costa, Anna M.,Faja, Montserrat,Farras, Jaume,Vilarrasa, Jaume

, p. 1835 - 1838 (2007/10/03)

The four possible 3'-uracil-1-yl and 3'-thymin-1-yl derivatives of 3'- deoxythymidine and the four analogous derivatives of 2'-deoxyuridine have been synthesised from thymidine and uridine, respectively. Advantages of the 2-(methoxycarbonyl)vinyl group to prevent the formation of anhydronucleosides and SnCl2/PhSH/Et3N in relation to H2/Pd for the reduction of most azido groups are disclosed.
