Web12 apr. 2024 · We report a novel route for the preparation of primary α-ketoamides via a highly efficient molecular iodine-mediated oxidative amidation of aryl methyl ketones with ammonium carbamodithioate. A self-sequenced iodination/nucleophilic substitution/Kornblum oxidation/amidation mechanism was proposed. WebSecondary amines react smoothly with 3-ketones to give enamines and good selectivity is achieved in the presence of 7-, 12-, 17- and 20-ketones. With pyrrolidine the reaction …
