    摘要: The invention relates to a process for the preparation, in a single step, of enones by an aldol condensation of a ketone, such as a gem-dimethyl cyclohexylethanone or gem-dimethyl cyclohexenylethanone derivative, with an aldehyde in the presence of a novel catalytic system and without the pre-formation of an enolate. Said catalytic system consists of a metal complex, such as a [(Cl)n(alkoxy)4-nTi] or [(Cl)n(alkoxy)4-nZr] complex (n being an integer from 1 to 3), and a co-ingredient, such as a carboxylic acid anhydride or an anhydrous salt.
