  An efficient synthesis for racemic cyclopent-3-en-1-yl nucleoside analogues has been developed starting from cyclopentadiene. The key step is the regioselective hydroboration of a mixture of intermediate alkylatede cyclopentadienes to give one cyclopentenol.

• Carbocyclic Analogues of 3′,4′-Didehydro-2′-deoxyribofuranosyl-2,4(1<i>H</i>,3<i>H</i>)-pyrimidinediones

  日期：1994.9

  A new method for obtaining carbocyclic analogues of 3',4'-didehydro-2,4(1H,3H)-pyrimidinedione nucleosides in good yields consists of the reaction of the carbocyclic 2,3'-anhydronucleosides with lithium chloride in dimethylformamide. Small amounts of the carbocyclic 2',3'-didehydro isomers are formed simultaneously. The carbocyclic 2,3'-anhydronucleosides were obtained by treating carbocyclic 5'-trityl derivatives with DAST.
