摘要

Another approach to a derivative of the formyl 9 that would be more stable under phosphorylation conditions is through the dithiolane analogue. Treatment of the protected formyl nucleoside 6 with ethanedithiol in a BF3-catalyzed reaction gave an 84% yield of 10. Basecatalyzed transesterification converted 10 to the nucleoside 11. The ultraviolet maxima of 11 at 270 nm is midway between the maxima for a 5-substituted CH3 or CHzOR ...
