4′,6′-Methano carbocyclic thymidine: A conformationally constrained building block for oligonucleotides
摘要:
The synthesis of the title compound I has been accomplished in 20 chemical steps starting from D-ribonolactone. X-ray crystallography shows the bicyclic skeleton of 1 to adopt a boat-like (''2'-exo'') conformation and preliminary hybridization data indicate that the substitution of 1 for natural thymidine in DNA/RNA heteroduplexes may increase their thermodynamic stability.
