3-deazaadenine) carbocyclic nucleosides, nucleoside 2',3'-dialdehydes, and nucleoside 2',3'-diols were synthesized as potential inhibitors of bovine liver S-adenosyl-L-homocysteine (AdoHcy) hydrolase (EC 3.3.1.1) and as potential inhibitors of vaccinia virus replication. The 2',3'-dialdehydes were prepared by periodate oxidation of the corresponding carbocyclic nucleosides. Reduction of the intermediate
