    • Dr was measured before purification, as epimerization on the asymmetric center in position 3 easily takes place on silica gel.

    • In these conditions, some variation of dr between the lactone and the iodohydrin was observed (Table 1; entries 4, 5, 7, and 8) without any rational explanation.
