    • 5, these protons shifted to the down shielded field, namely, the amide proton at 6.9 ppm and two distinct hydroxyl protons at 4.4 and 4.7 ppms (ratio of 1.7:1), respectively, while the chemical shifts of other protons of trans-2 remained more or less unchanged. The downfield shifts of carbamate NH and observed two values for OH protons in THF clearly indicate a solvation of 2 by THF, giving rise to at least two different solution species.

    • note
    • 16 All three referees of this paper commented on the use of the DFT/B3LYP/6-31G* level of theory to calculate the input geometries for the OR calculations. This choice has been made considering that a large part (probably the largest part) of the OR computations described in the literature employ geometries obtained at this level of theory as a good compromise between accuracy and computational efforts.
