Abstract
The synthesis of 6, 3'-methanouridine was achieved by condensation of 2, 4-dimethoxy-6-lithiomethylpyrimidine with 5-O___--(tert-butyldi-methyl)silyl-1, 2-O___--isopropylidene-3-ketoxylose, followed by intramolecular glycosylation and deprotection. 6, 3'-Methanocytidine was also prepared from the 4-O___--methyl intermediate. The title compounds are the first example of uridine and cytidine fixed between C-6 and the 3'-position of pyrimidine nucleosides by a methylene group.
