alpha-lithiated 1-(1-alkenyl)benzotriazoles, generated from the reactions of 1-(1-alkenyl)benzotriazoles with n-BuLi, react with a variety of electrophiles to afford alpha-substituted 1-(1-alkenyl)benzotriazoles which undergo epoxidation with m-CPBA followed by hydrolysis to give alpha-hydroxy ketones in good yields. Thus, 1-(1-alkenyl)benzotriazoles behave as alpha-hydroxyacyl anion equivalents.
