| Abstract: | A new synthesis of enamides from ketones is disclosed that involves a phosphine-mediated reductive acylation of oximes. The resulting enamides are isolated in good yields (up to 89%) and excellent purity, permitting a subsequent hydrogenation to access enantiopure acetamides at catalyst loadings practical for large-scale applications. |
