Abstract
The synthesis of branched and conformationally restricted analogs of the anticancer nucleosides 3'-C-ethynyluridine (EUrd) and 3'-C-ethynylcytidine (ECyd) is presented. Molecular modeling and (1)H NMR coupling constant analysis revealed that the furanose rings of all analogs except the LNA analog are conformationally biased towards South conformation, and are thus mimicking the structure of ECyd. All target nucleosides were devoid of anti-HIV or anticancer activity.
