RESUMEN

Difluorinated cyclohexene diols (prepared from trifluoroethanol) can be elaborated to racemic analogues of phosphorylated sugars via regioselective protection and phosphorylation of the exposed C-1 hydroxyl group. Cis-diol protection was achieved using stannylene methodology, though the regioselectivity depended on the orientation of the methyl group at C-5. UpJohn dihydroxylation is effective with the phosphotriester in place and global deprotection to the tetrol monophosphates is efficient.
