    • note
    • Moderate 3.5-cis-selectivity (cis/trans = 5) has been observed in the reaction of bicyclic lactam enolate with a small electrophile such as MeI, while under the same conditions, the reaction with other electrophiles such as allyl bromide and benzyl bromide proceeded in a nonselective manner or with low 3,5-trans-selectivity. See refs 5f, 5j, and 5k.
