摘要:A novel method has been found to produce 2,2′-anhydro-1-(β-L-arabinofuranosyl)thymine as a novel useful intermediate compound. A novel method has been further found to produce thymidine from 2,2′-anhydro-1-(β-L-arabinofuranosyl)thymine. A novel method has been further found to L-2′-deoxyribose derivatives as a useful synthetic intermediate through L-2,2′-anhydro-5,6-dihydrocyclouridine derivative. According to these methods, synthesis of various L-nucleic acid derivatives, synthesis of which has been difficult till now.

摘要:A process of preparing 6-O-alkyl erythromycin A is provided. The process includes the steps of protecting the oxime hydroxyl of 9-oxime erythromycin A with a benzoyl protecting group, protecting the 2'-hydroxyl group and optionally the 4'-hydroxyl group with an O-protecting group, alkylating the 6-hydroxyl, removing the benzoyl and O-protecting groups and deoximating the 9-oxime.
