During the revision of this Article prior to publication, a computational study was reported (Vallejos, M. M. & Pellegrinet, S. C. Theoretical study of the BF3-promoted rearrangement of oxiranyl N-methyliminodiacetic acid boronates. J. Org. Chem. 82, 5917–5925; 2017) that evaluates the nucleophilic boryl transfer mechanism predicted in this Article; this reference has now been added as number 19, and the subsequent references renumbered.
