a

Our previous report23 provided kobs values from linear fits of the curved integrated rate data for the fragmentation of the mixture of diastereomers taken to 90% completion. Herein, we report more representative kobs values obtained from the reaction taken to 50% completion.

b

Diastereomer ratios were determined from 1H NMR resonances of alkene protons.

c

1H NMR resonances for the signals corresponding to d1 and d2 were slightly overlapping.
