Facile synthesis of α-anomeric pyrimidine nucleosides

Sawai,Nakamura,Hayashi,Shinozuka

, p. 1647 - 1654 (2007/10/02)

2-Amino-α-D-ribofurano[1',2':4,5]-2-oxazoline reacted with α- bromoacrylonitrile yielding 2,2'-anhydro-1-α-D-ribofuranosylcytosine which was converted to α-cytidine and α-2'-deoxycytidine. Reaction of 2-amino- α-D-ribofurano[1',2':4,5]-2-oxazoline and ethyl α-(bromomethyl)acrylate afforded 2,2'-anhydro-1-α-D-ribofuranosylthymine, a precursor of α- thymidine and α-ribothymidine.
