Several compounds of a new series of cyclohexane-based 1,2-disubstituted carbonucleoside analogues, were synthesized. The adenine and uridine derivatives, were prepared by construction of the heterocyclic base on the primary amino group of 2-aminocyclohexylmethanol, and the thymine derivative by condensation of 2-hydroxycyclohexylmethanol with thymine using the Mitsunobu reaction.
