A novel process for preparing 2,2'-anhydro-1-(ß-L- arabinofuranosyl)thymine which is novel and a useful intermediate; a novel process for preparing L-thymidine from 2,2'-anhydro-1-(ß-L-arabinofuranosyl)thymine; and a novel process for preparing an L-2'-deoxyribose derivative useful as an intermediate through an L-2,2'-anhydro-5,6-dihydrocyclo- uridine derivative. These processes enable the synthesis of various L-nucleic acid derivatives which were difficult of synthesis. |
