Synthesis in dry media coupled with microwave irradiation : Application to the preparation of enaminoketones.
摘要:
Beta-diketones react with a variety of amines and aminoesters over clay K10 or silica under microwave irradiation in open vessels to give within a few minutes, the corresponding enaminoketones with good yields. According to the reaction conditions acylamines may also result.

A variety of β-enaminoketones and esters have been synthesized in high to exellent yields by reacting β-dicarbonyl compounds with amines in the presence of a catalytic amount of indiumtribromide. The reaction proceeds smoothly at room temperature in a short reaction time under solvent-free conditions.
