Racemic or chiral p-amino alcohols and diols were coupled with methyl difluoro(diethoxyphosphono)dithioacetate to give the corresponding p-hy-droxythioaminides. These intermediates were then cyclised under Mitsunobu conditions in the presence of either 6-chloropurine or 3-benzoylthymine to yield nucleosidic base-derived thiazolines linked to a difluoromethylphosphonate diester (88a, b).

As described previously for trifluoromethyl ethers, Umemoto [23c] reported on the trifluoromethylation of thiols with -(trifluoromethyl) dibenzothiophenium triflate affording the corresponding trifluoromethyl thioethers in medium to good yield. Otherwise, trifluoromethyl phenyl thioethers and ring-substituted analogs are readily made from iodo- or bromoarenes, methyl difluoro(fluorosulfonyl)acetate and elemental sulphur in the presence of cuprous iodide in hexamethylphosphoric triamide (HMPA) or A-methylpyrrohdone (NMP) (Scheme 10).
