标 题:Synthesis of cyclopentenones
发明人：JACOBY DENIS; KELLER FABRICE
权利人:FIRMENICH & CIE
摘要:The invention relates to a process for the preparation, in a single step, of substituted 2-cyclopenten-1-ones by reacting a substituted enone with an aldehyde in the presence of a catalytic system. The catalytic system consists of a metal complex, such as a Ti(Cl) 3 (alkoxy), and a co-ingredient, such as a carboxylic acid anhydride or an anhydrous salt.

摘要:The invention relates to a process for the preparation, in a single step, of substituted 2-cyclopenten-l-ones by reacting a substituted enone with an aldehyde in the presence of a catalytic system. Said catalytic system consists of a metal complex, such as a [Ti(Cl)₃(alkoxy)], and a co-ingredient, such as a carboxylic acid anhydride or an anhydrous salt.
