Acetylation of the title enamino ketones with acetylchloride was carried out in pyridine or ether with an without base. N-acetyl derivatives were obtained in pure ether, but activation of O and C nucleophilic centers was promoted by the presence of base. Electronic and structural factors governing regioselectivity of reaction are discussed.
