Computational assessments of diastereoselective [4+2] cycloaddition and 1,3-borotopic shift of a dearomatized tertiary boronic ester intermediate: reactivities explained through transition-state distortion energies

Interception of a dearomatized tertiary boronic ester, formed through a kinetically and thermodynamically favorable 1,2-metalate rearrangement/ anti -S N 2′ elimination of an activated ortho -lithiated benzyl amine, in a [4+2] cycloaddition or 1,3-borotopic shift has been investigated by density fun...
