Synthesis of new carbocyclic analogs of 1-(2′,3′-dideoxy-glycero-pentofuranosyl)pyrimidine nucleosides having the uracil (34), 2-thiouracil (33), 2-thiothymine (31), cytosine (44), and 5-methylcytosine (43) bases is described. The nucleoside analogs having the uracil, 2-thiouracil, and 2-thiothymine bases were prepared by coupling cis-3-aminocyclopentanemethanol (8) with 3-ethoxypropenoyl isocyanate

Aminohydroxycyclopentanemethanols are important precursors for the synthesis of cyclopentane analogs of purine and pyrimidine nucleosides. The regiospecific synthesis of two new aminohydroxycyclopentanemethanols, 17 and 22, is described. In these syntheses the desired configuration in the cyclopentane ring is obtained by opening the cis-acetoxy-1,3-cyclopentanedicarboxylic acid anhydride 3 with either
