Autor: Igor A. Mikhailopulo, Grigorii G. Sivets, Tatjana V. Klennitskaya, Elena V. Zhernosek

Publikováno v: Synthesis. 2002

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 ar
