Unsaturated acyclic pyrimidine analogues, 1-1-[1-(hydroxymethyl)prop-2-enyloxy]prop-2-enyl}uracil, 1-1-[1-(hydroxy-methyl)prop-2-enyloxy]prop-2-enyl}thymine and 1-1-[1-(hydroxymethyl)prop-2-enyloxy]prop-2-enyl}cytosine having two asymmetric carbon atoms have been prepared in good yield starting from uridine and 5-methyluridine. The bis-vinyl thymine derivative underwent ring closure metathesis to give d4T, thus providing a novel synthesis of this compound. (C) 2003 Elsevier Science Ltd. All rights reserved.
