auracil (12) by using standard deoxyribosidation methodology. Compound 7 was prepared from 5-(3-furyl)-6-azauracil (33) via a ribosidation/deoxygenation sequence. An attempt to prepare the corresponding 5-(2,2-difluorovinyl) analogue afforded instead a mixture of the 5-[(2,2-difluoro-2-methoxy)ethyl] and 5-(2,2,2-trifluoroethyl) derivatives 29 and 30. Compounds 2-7, 29, and 30 were tested for in vitro
fed to various somatic cell lines and induced mouse embryonic stem cells, together with a 2′‐fluorinated fdC analogue (F‐fdC). While deformylation of F‐fdC was clearly observed in vivo, it did not occur with a‐fdC, thus suggesting that the C−C bond‐cleaving deformylation is initiated by nucleophilic activation.
