reduction of the corresponding (E) amide rotational isomer under identical conditions provides only the reduced product, (E)-N-allyl-N-(2,4,6-tri-tert-butylphenyl)acetamide. Such diverging reactions of rotamers may be common in transformations involving reactive intermediates (carbenes, radicals, organometallic intermediates) that have low barriers to onward reactions relative to amide rotation.
