Abstract
A practical synthesis of peracylated derivatives of β-l-ribofuranose 13-15 from d-ribose was accomplished in 6 steps (total yield: 30-45%). Compound 13 was employed for the preparation of 1-(β-l-ribofuranosyl)thymine (16) and -cytosine (17), which are key intermediates for the preparation of the nucleoside derivatives with β-l-configuration. Simultaneous transformation of 17 into β-l-ddC (19) and β-l-3’dC (20) was studied.
