Dynamic effects on [3,3] and [1,3] shifts of 6-methylenebicyclo[3.2.0]hept- 2-ene

(Figure Presented) Deuterium labeling experiments on the rearrangement of methylenebicycloalkene 1 to 3 show stereoselectivity despite the intermediacy of a stabilized diradical structure 2. A theoretical model built from computational studies explains the observed product ratios. Stereoselectivity among [3,3] (minor) products implicates an unusual bifurcation of reaction trajectories after the initial bond-breaking transition state.
