Method for preparing 2-(cyclohexenylidene) malonic acid derivatives and uses thereof
Disclosed are a method for preparing 2-(cyclohexenylidene) malonic acid derivatives and uses thereof. In this method, an olefin and a 2-substituted malonic acid derivative are used as starting materials to prepare the 2-(cyclohexenylidene) malonic acid derivative in the presence of a catalyst through cyclization reaction. This method has the following advantages: (1) the method can be very efficiently used for the synthesis of highly sterically-hindered 2-(2,6-disubstituted cyclohexenylidene) malonic acid derivatives; (2) the reaction yield is high, the reaction conditions are mild, and the wastes are less, favorable for industrial production. More importantly, the present invention extends the further use of 2-(cyclohexenylidene)malonic acid derivatives in organic synthesis, especially in the synthesis of 2-aryl malonic acid derivatives and their corresponding drugs such as Pinoxaden.
