    • 1H-NMR spectroscopy. There is no evidence for mutual rearrangement of the regioisomers by acyl shift.

    • note
    • A kind of "zip reaction" does definitely not occur during the purification of the product mixture as, after benzoylation of the crude mixture, the corresponding N-benzoylated ester could not be detected in the NMR spectra.

    • note
    • In the case of the adducts formed with 2-(methylamino)ethanol, the yields dropped significantly (from quantitative to 65%) when the reaction times were increased from 3 to 18 h. Also, the ratio of the two regioisomers was shifted somewhat during chromatography.

    • The presence of the a lithium salt proved to have no effect on the yields and selectivities found in this reaction, but the improved solubility of the sugar (vide supra) made its use as an additive advantageous.
