“…We concluded that small amounts of water in reagent grade DMF (entry 7) may lead to in situ MIDA ester cleavage due to possible (basic) dimethylamine generation. 28 The result employing acetonitrile (entry 1), although comparable to that of Entry 6, was deemed to be the most promising, due to the reduced toxicity and lower boiling point of this solvent. 29,30 Interestingly, the use of molecular sieves (entry 2) did not push the reaction to completion.…”

“…All 1 H NMR spectra were identical, presenting well-characterized signals in the aliphatic area and a sharp singlet around 8.00 ppm, without any characteristic signals for aromatic protons. At that point we realized our mistake, DMF being known to be ''much more than a solvent'', as pointed out by Muzart [8] and namely known as a slow formylation reagent for both aromatic and aliphatic amines [9]. Therefore, the natural conclusion was that a reaction indeed took place and that the reagents in that process were HMDA and DMF, without any participation of the less reactive ketones.…”

“…With this modulated glycosylation method, DMF is employed to entrap the cationic glycosyl oxacarbenium ion as a glycosl imidate. [19,20] Further reaction of the imidate with an acceptor produces the desired cis a-glycoside in high selectivity. Because the modulation method includes a pre-activation step, it is further elaborated to iterative glycosylation for thioglycosyl substrates.…”
