of evaluation of carbocyclic ribonucleoside-containing oligonucleotide therapeutics, we developed convenient, scalable syntheses of all four carbocyclic ribonucleotide phosphoramidites and the uridine solid-support building block. Crystallographic analysis confirmed configuration and stereochemistry of these building blocks. Duplexes with carbocyclic RNA (car-RNA) modifications in one strand were less

Carbocyclic analogues of ribofuranosides of 2-amino-6-substituted-purines and of 2-amino-6-substituted-8- azapurines were prepared from the 2-amino-6-chloropurine ribofuranoside analogue (2) and the 2-amino-6-chloro-8- azapurine ribofuranoside analogue (9), respectively. Analogues of purine ribofuranosides with the chloro, amino, methylamino, or methylthio group at position 6, the thioguanosine analogue
